I observed as best I could if it may be a hard downshift of some sort (regardless of what M mode the car is in), by ensuring the gear number was visible in the cluster and seeing if this phenomenon occurs precisely at the time when a downshift occurs. It actually does not, and the whole thing could best be described as though the car has a vacuum leak somewhere causing it to lurch forward (it doesn’t, but just “feels” that way).

Is this notchiness normal in these cars, and if not, then any ideas?

Thanks!
No No No thats not right, I have had all 4 F90 M5's from 2018/19 to my new 2022 M5 5 weeks old, that is not right and sounds like a mates car and he had the gearbox software updated to cure it.
None of my F90 ever did that.
