Anyone can help me to locking/ disabling the Appearance -> Customizer -> Additional CSS area. on Wp-admin.
I read this codex https://codex.wordpress.org/Theme_Customization_API But didn't got any hook or function for disabling it. Actually, I don't need this, anyone developer's adding unnecessary CSS from here and this saving on the database. Please suggest any solution, If that is possible to do.
Thank you in advance for your valuable reply.
