Tips on keeping stage and prod in alignment?

Hello developer friends!

I am newer to GitHub, so please forgive me if I use the wrong terms here. :)

I was wondering if anyone had any tips or tricks on how to "roll back" stage changes to bring staging back in line with prod on a regular basis? I've searched for how to do this more broadly, but what I've found doesn't seem to align well with a situation like Khoros, where there are a few developer admins with GitHub access, but everyone else is making changes directly on the site UI.

Essentially, I want to be able to "undo" any unnecessary changes on Stage from people testing or experimenting before say, a Khoros update, so that we can test the new version with the site mirroring Prod as closely as possible.

Any advice is welcome - and thanks in advance! :)
