Custom CSS to replace functions.php fix?

Hello,

Is there a way to modify my Custom CSS to replace the following functions.php fix?

remove_action( ‘woocommerce_before_shop_loop’, ‘woocommerce_catalog_ordering’, 30 );

I need to add this to the functions.php anytime I upgrade to a new version of Catch Everest Pro because I cannot find a way to implement it in Custom CSS.

It removes the WooCommerce ‘Sort By’ dropdown on my Shop page and simply adding this code to my Custom CSS does not work. For one reason or another, it needs to be in functions.php for it to work…

Thanks for your help.
