Hi,

Sorry, the only method at the moment is to add this code in your theme or child-theme functions.php file:

delete_option('stec_user_fa_icons');

Once the changes are applied you should remove it.

---

If you are planning to use only certain icons you could insert all desired icons via filter. 

Example:

add_filter('stec_icons', function($old_icons_array) {
    $new_icons = array(
        'fa-solid fa-times' => 'Close icon',
        'fa-solid fa-user'  => 'User icon',
        // and so on...
        // ...
        // ...
        
      
    );
    return $new_icons;
});

This filter should be placed in your theme or child-theme (whichever is active) functions.php file.
