In fairness, you can disable the admin service if you want, then it just makes Django a big fat bloaty library.

But more to the point, I feel like DRF is kind and of a weird solution anyway, like the request object is different from Django, it doesn't support schema generation without some third party libraries...

Frankly, FastAPI with an orm sounds like the ultimate python microservice framework, anyway. Pgcli works as an admin interface in a pinch.
