Remove an action from an external plugin class

I am trying to remove an action from a plugin class WC_GFPA_Entry which has following lines of code:

add_action( 'gform_entry_detail_content_before', array( $this, 'entry_detail_screen_notice' ), 10, 2 );

Here is the Class code:

class WC_GFPA_Entry {

private static $instance;

public static function register() {
    if ( self::$instance == null ) {

        if ( apply_filters( 'woocommerce_gravityforms_create_entries', true ) ) {
            self::$instance = new WC_GFPA_Entry();
        }
    }
}

private $_resuming_orders = array();

private function __construct() {

    add_filter( 'gform_entry_detail_meta_boxes', array( $this, 'add_custom_entry_metabox' ), 10, 3 );

    add_action( 'gform_entry_detail_content_before', array( $this, 'entry_detail_screen_notice' ), 10, 2 );

}

public function add_custom_entry_metabox( $meta_boxes, $entry, $form ) {
    // some code 
}

public function entry_detail_screen_notice( $form, $lead ) {
    // some code .....
}
}

What I have tried in functions.php so far:

remove_action( 'gform_entry_detail_content_before', array( WC_GFPA_Entry::register(), 'entry_detail_screen_notice' ), 10, 2 );

And:

function remove_action(){
    remove_action( 'gform_entry_detail_content_before', array( WC_GFPA_Entry::register(), 'entry_detail_screen_notice' ), 10, 2 );
}
add_action('init', 'remove_action');

I have also tried changing priority etc but nothing really worked. Any help would be appreciated.

Unfortunately, there is no easy way of doing this. However, it is doable by using an utility like this:

https://github.com/herewithme/wp-filters-extras/blob/master/wp-filters-extras.php

So in your example that would be:

remove_filters_for_anonymous_class('gform_entry_detail_content_before', 'WC_GFPA_Entry', 'entry_detail_screen_notice', 10)

Lib code above:

function remove_filters_with_method_name( $hook_name = '', $method_name = '', $priority = 0 ) {
    global $wp_filter;
    // Take only filters on right hook name and priority
    if ( ! isset( $wp_filter[ $hook_name ][ $priority ] ) || ! is_array( $wp_filter[ $hook_name ][ $priority ] ) ) {
        return false;
    }
    // Loop on filters registered
    foreach ( (array) $wp_filter[ $hook_name ][ $priority ] as $unique_id => $filter_array ) {
        // Test if filter is an array ! (always for class/method)
        if ( isset( $filter_array['function'] ) && is_array( $filter_array['function'] ) ) {
            // Test if object is a class and method is equal to param !
            if ( is_object( $filter_array['function'][0] ) && get_class( $filter_array['function'][0] ) && $filter_array['function'][1] == $method_name ) {
                // Test for WordPress >= 4.7 WP_Hook class (https://make.wordpress.org/core/2016/09/08/wp_hook-next-generation-actions-and-filters/)
                if ( is_a( $wp_filter[ $hook_name ], 'WP_Hook' ) ) {
                    unset( $wp_filter[ $hook_name ]->callbacks[ $priority ][ $unique_id ] );
                } else {
                    unset( $wp_filter[ $hook_name ][ $priority ][ $unique_id ] );
                }
            }
        }
    }
    return false;
}
/**
 * Allow to remove method for an hook when, it's a class method used and class don't have variable, but you know the class name :)
 */
function remove_filters_for_anonymous_class( $hook_name = '', $class_name = '', $method_name = '', $priority = 0 ) {
    global $wp_filter;
    // Take only filters on right hook name and priority
    if ( ! isset( $wp_filter[ $hook_name ][ $priority ] ) || ! is_array( $wp_filter[ $hook_name ][ $priority ] ) ) {
        return false;
    }
    // Loop on filters registered
    foreach ( (array) $wp_filter[ $hook_name ][ $priority ] as $unique_id => $filter_array ) {
        // Test if filter is an array ! (always for class/method)
        if ( isset( $filter_array['function'] ) && is_array( $filter_array['function'] ) ) {
            // Test if object is a class, class and method is equal to param !
            if ( is_object( $filter_array['function'][0] ) && get_class( $filter_array['function'][0] ) && get_class( $filter_array['function'][0] ) == $class_name && $filter_array['function'][1] == $method_name ) {
                // Test for WordPress >= 4.7 WP_Hook class (https://make.wordpress.org/core/2016/09/08/wp_hook-next-generation-actions-and-filters/)
                if ( is_a( $wp_filter[ $hook_name ], 'WP_Hook' ) ) {
                    unset( $wp_filter[ $hook_name ]->callbacks[ $priority ][ $unique_id ] );
                } else {
                    unset( $wp_filter[ $hook_name ][ $priority ][ $unique_id ] );
                }
            }
        }
    }
    return false;
}
