I've had great success with Pop_OS! and hybrid graphics on my laptop (RYZEN 6800H/RTX 3070). If its related to the high power gpu not swithing at all.
The Nvidia iso might be worth a try.
For those that don't want to click through:

Setup looks great and gals that Pop_OS worked you for you in the end.
