Why do you need to change to gen 3 instead of 4?
I had a similar issue but mine was trying to go from gen 3 to 4. I had a a gen 3 m.2 in originally and then swapped it out for a gen 4 drive but the board would only seen it as a gen 3 driver no matter what settings I applied in bios.
Cmos reset fixed the issue for me
