I think you may have other issues. Personally, I don't recall ever seeing a BSOD updating AMD drivers. That's thinking back to ye olden Vega64 days, to 6700XT, to my current 6900XT. On Windows 10 and now Windows 11. If the undervolt is giving you a black screen then that would point to the undervolt not being stable. That's not an AMD driver issue - that could just be down to poor silicone. You are not going to get "more" issues with AMD vs Nvidia. All I can safely say is, go have a read of the Nvidia drivers thread, do some reading on XDA, and those sorts of sites, and make up your own mind whether you think Nvidia drivers seem stable.
