Just want to say that.. Anyone sleeping on this particular post.. This is IT for me, seemingly. Survived multiple reboots, shutdowns etc. I wasn't able to get my (new) SBz to stick around after reboots at all.. Possibly because of my weird multi screen, many sound output setup shunting everything around and causing it to rethink its addresses or something, I don't know? I can't even begin to understand how or why its behaved this way..Reading around I tried a load but the thing that currently seems to be working for me utilises local group policy to prevent windows updating the drivers. Mine has been stable through a few reboots now.
Requirements - The card must be in a functioning state for this to work - I ended up moving it to a new PCI slot as it seems to work the first time, its subsequent reboots etc where it breaks.

Im on an ASUS Strix B550-F.. Running the latest official drivers. It just would not stay visible! Now it does. I'll come report back if it breaks again, I guess. I bet some future windows update kills it again but at least I know what to fix if it does? Thankyou @wiggum123 !
