Prefab has something that you could use in more or less this way. The value of the flag can come from different sources and there is a defined order precedence. The base levels are default yaml files, which would be committed in your project. We think of live values from the server as a "potential override". So if you only wanted things in git you could just not use the UI. Details in https://docs.prefab.cloud/docs/explanations/bootstrapping

I'm spike-ing on some similar/adjacent things right now actually if you want to jam. I won't claim that what exists today is very polished for your usage pattern.
