Hi there,
you can globally disable proteo google font styles adding this snippet of php code in your child theme functions.php file
/**
* Disable google font stylesheet
*
* @return void
*/
function yith_proteo_customer_remove_google_fonts() {
wp_dequeue_style( 'yith-proteo-google-font' );
wp_dequeue_style( 'yith-proteo-custom-google-fonts' );
}
add_action( 'wp_enqueue_scripts', 'yith_proteo_customer_remove_google_fonts', 100 );
To host locally your webfonts, like also google fonts, you can download theme and place the files in a folder of your child theme. Then you can simply load them throught the child theme style.css or via Additional CSS code.
I’m also pointing you to this webpage which give a nice example: https://wplift.com/how-to-host-google-fonts-locally-on-wordpress
The part of the article about disabling google fonts on your theme is already covedere with the PHP code above.
