Change Table Values via "Expand Row" Modal Only

We would like to allow specific users to be able change table values via the “Expand Row” modal window only — not via the table directly. I think this may be similar to an edit-lock request posted March 2019 (see URL below), but was wondering if these kind of locking restrictions/granular permissions will be possible, and if so, is there a timeline for their roll-out?
