The installation process sets it up to you. You'd have to do more work to not have dual-boot (unless there was a setting in the installer that I forgot).
I'm not parent, but from my quick foray into (Fedora) Asahi on a Macbook Air M2, I at least noticed USB-C connection to my monitor and USB router behind it not working at all. There's something Mac-specific going on there, because from my x86-based linux laptop, this usually works fine.
