You are missing the code to save the selected driver's id in order meta while saving the order after selecting driver.

I've not tested the code but hope it helps.

add_action( 'add_meta_boxes', 'add_meta_boxes' );

function add_meta_boxes()
{
    add_meta_box( 
        'woocommerce-order-my-custom', 
        __( 'Order Driver' ), 
        'order_my_custom', 
        'shop_order', 
        'side', 
        'default' 
    );
}
function order_my_custom()
{ 
  global $woocommerce, $post;
  $order_id  =$post->ID;
  $servername = "localhost";
  $username = "root";
  $password = "no_password";
  $dbname = "testtable";

  $conn = new mysqli($servername, $username, $password, $dbname);
  // Check connection
  if ($conn->connect_error) {
      die("Connection failed: " . $conn->connect_error);
  } 

  $sql = "SELECT * FROM wp_posts WHERE post_type='drivers'";
  $result = $conn->query($sql);

  if ($result->num_rows > 0) {
    ob_start();?>
   <select name='order_driver' style='width:100%;' >
    <option value=""> --- Select ---</option>
    <?php
    while($row = $result->fetch_assoc()) {
        $order_driver = get_post_meta($order_id,'order_driver',true);
    ?>
    <option <?php echo ($row['ID']==$order_driver)?'selected':''?> value="<?php echo $row['ID']?>"><?php echo $row['post_title']?></option>

  <?php  } ?>
   </select>
  <?php } else {?>
   <option value="">0 Results</option>
    <?php }
    echo ob_get_clean();
$conn->close();

} 

function save_drivers_meta( $post_id, $post, $update ) {

    $post_type = get_post_type($post_id);

    /*
     * Make sure we are updating post meta only for shop orders
     */
    if ( "shop_order" != $post_type ) return;

    // - Update the post's order_driver value if it's set.

    if ( isset( $_POST['order_driver'] ) ) {
        update_post_meta( $post_id, 'order_driver', sanitize_text_field( $_POST['order_driver'] ) );
    }
}
add_action( 'save_post', 'save_drivers_meta', 10, 3 );
