I have a very specific situation. In the courses I'm developing we want to have multiple teachers in a course, but with access only to their own sections of the course. I do know how to assign teachers to specific sections, and how to make it so that they can only see their own section, but the issue is that they could simply change their own privileges in the User Details screen to then give them access to all sections again.
I need to be able to take away that permission, but I have no idea how.
I have attached a screenshot of the spot that they should not be able to select.
