On the same sdcard?
You could use PINN for multi boot and try to migrate the raspios partition there but tbh if you don’t want to reinstall I thin it’s easier and safer to keep each os install to a different sdcard. They are simply too cheap.
Yeah, why bother? If I want to try something new on the pi I just spin up a new card. Having said that, there’s usually a way to do a bare metal install for most things and there are usually instructions for that on the project page.
