Any good ways to prevent non-Steam/Lutris games from breaking when updating SteamOS?

I have a steam deck on SteamOS 3.3.1. It has worked well for me and I didn't plan on updating until I saw that new versions of SteamOS will be able to download with the screen off. I'm worried that all the hard work I put in getting non steam games to work and installing via Lutris etc. will have to be repeated if I update. Am I over-reacting or should I just stay on 3.3.1?
