Validate CSV with different delimiters in Laravel, fileinfo

Intro

I've got two files and I'm trying to post them to an endpoint via cURL.

file1.csv

header1,header2
row1_value1,row1_value2
row2_value1,row2_value2

file2.csv

header1;header2
row1_value1;row1_value2
row2_value1;row2_value2

Only file1.csv passes the validation rule mimes:csv.

curl -F "[email protected]" -X POST http://host/api/endpoint

I've tracked down the method that causes the validation to fail. It's in Symfony's FileinfoMimeTypeGuesser which in turn just does

(new \finfo(\FILEINFO_MIME_TYPE, null))->file($path)

The question:

Is it possible to make finfo consider csv's delimited by a non-standard character, such as a semicolon ;, to be considered as a csv file so both of my example files pass Laravel's 'mimes:csv' validation?

I'm unfamiliar with how finfo works under the hood, but there is an optional $magic_database argument that can be passed in.
