I use the following to hide the global search on my own platform but you would need more logic than CSS can provide to only hide it for select individuals.

/** Hide the global search **/

doc-layout-global-search-boxed .global-search-boxed-submit, .global-search-boxed-input{
    visibility: hidden;
}

Thanks, gstager. That was very helpful.

@gstager Thank you! this is perfect and then hopefully we can figure out how to manage the courses and report access. 

After using that CSS for hiding the search, I think if you adjust the power users permissions to view courses and view enrollments, but not allow to create enrollments or activate enrollments, that should let them see enrollment progress, but restrict them from enrolling themselves.  You might have to test and play with those permissions a little bit.

Thank you @Annarose.Peterson I will test this with these permission restrictions too.

I ended up giving one manager permissions so they could see only see My Teams but nothing else (and no global search).

The other one is setup as a Power User but it is complicated because they need to access Course Management to manage their courses but also be able to see the enrollment progress for all courses (not just those they manage) so it has been difficult because the reports permissions for a Power User doesn’t all me to select which courses/catalogs they can view. In order for them to see all course progress they need access to the catalogs and in turn also have access to edit those in Course Management as well.
