That I’m not sure of. However, even if you could the price of the RF lenses are astronomical. If one can afford to purchase RF lenses then they can afford to buy a higher end camera than the M50. That would be my view.

The magic words I always look for are "phase detect auto focus". It's a lifesaver! (y) Sony and Olympus cameras have had it for the last few years. Sony is definitely the king of autofocus, but not necessarily easy to use. Panasonic should be avoided as it's terrible in many ways. But really it boils down to what budget you have and what you plan to shoot. Depending on that, the best option could be a £5000 cinema camera or a £300 360 degree action cam.
what camera do you guys recommend for video and pics
