1. Our course content (like modules, assignments, and quizzes) is pre-loaded from an external tool, and the course settings are set by our course admins.
2. Teachers only need to grade and collaborate with students, so we’ve turned off all options for them to add, edit, or delete course content or any other type of setting.
3. We’ve only allowed teachers to edit/manage student grades.
4. We have disabled many unused navigation menus, but since "Settings" tab in the left-hand menu is still visible to teachers they might change the course settings, making it hard for our course admins to keep track and revert to original settings.
5. We also removed all permissions from the TA role and assigned it to teachers, but the "Settings" tab still shows up for TA role.
6. Is there any way to disable the tab Teacher/TA role? If we were to create a custom role, what would be the the recommend role to base it off of?

Any help would be appreciated! 

Thank you!
