Disable expert mode and choose buttons to show in page titlebar

I have seen this question which is dated back to 2016. Did anything change since then with the regard to disabling editing modes?

As this is just a one page modular site I do not need the current advanced functionality. I am aiming to disable expert mode along with disabling add, copy, move and delete buttons.

If it is not possible to disable the editing mode and buttons completely it will be great to disable them based on the user role.

How can I achieve that?
