As long as the bootloader does not break, which is highly likely, you can have both OSs on your main computer and progressively boot into Linux as you feel more comfortable.

If you're running on M1/M2 I believe the only option atm is Asahi who are developing all drivers for these specific models, so you won't be hammering out driver issues, instead you will be waiting for support: https://github.com/AsahiLinux/docs/wiki/Feature-Support

I strongly recommend trying Linux out on a second computer (e.g. a used Apple laptop) before trying it on your main Apple computer. That way, you can comfortably hammer out any hardware/driver issues and experiment with Linux -- while still being able to do work with your main computer.
