Hi @mynetflixtain,
If you go to your Dashboard -> Profile Builder -> Settings -> and in Allow Users to Log in With: you select Email, then the username field will be hidden from all the front-end PB forms (Edit Profile, Registration, Log-in, Recover Password).
If you want to hide other fields in the Edit Profile form then that is possible in the free version of Profile Builder. Since we are not allowed to speak about the paid versions here, in case you would like to have that conversation please open a support ticket using our site: https://www.cozmoslabs.com/support/.
Best regards,
