How do I prevent my teachers from being available for self-booking?

Enabling Teacher Availability Control: Restricting Self-Booking Access for Teachers

To hide your teacher's availabilities when clients go to self-book, navigate to the teacher's profile and click Update Profile.

Scroll down to the bottom of the page. Toggle off both Can visitors see this staff? and Can clients see this staff? to hide your teachers' availabilities from clients and visitors. Toggle on Can clients see this staff? if you wish to only show teachers' availabilities to current clients.
