NVMe found/detected/recognized in BIOS but not found/detected/recognized by Windows 10 / Windows 11

I've seen similar posts scattered over the internet and no real solutions. The issue seems to be specific to AMD processors and respective motherboards. I've seen most posts related to MSI boards but I doubt it's limited to them.

Scenario:

You install a second NVMe drive onto your motherboard, your BIOS sees the drive, but Windows does not in Device Manager or Disk Management.

I've done everything from messing around with the BIOS to buying a PCIe NVME Riser to make sure it wasn't a bad NVMe connection. I know my MSI x470 Gaming Plus board supports 2 drives, this was not related to a disabled SATA port, or a drive support/compatibility issue. Nothing worked and I refused to reinstall Windows as a solution (as I've seen in other posts recommending). After spending way too many hours on this problem, I finally found the solution to my specific issue and it's all related to the "AMD-RAID Bottom Device" Controller Drivers that the AMD chipset software installs. For whatever reason, this AMD driver and Windows do not get along. The solution is to change/update the driver to the Standard NVME controller that comes with Windows.

Solution:

-Device Manager -> Storage Controllers -> Expand

-Find AMD-RAID Bottom Device -> Right Click -> Properties -> Driver -> Update Driver

-Browse From My Computer -> Let me pick from a list -> Select Standard NVM Express Controller -> Next

-Within 2 seconds, everything seems to be working without any issues.

I posted this so the internet will archive this for future use. Hopefully this helps someone out there who's had similar issues. Or runs into them randomly after an AMD Chipset update.

Update (7/19/2022):

Happy to see people getting value from this post. After doing some investigation, it seems like the AMD chipset drivers install the AMD-RAID Bottom Device drivers. For some unknown reason, Windows defaults to those drivers and it shouldn't. It should be using the Standard NVM Express Controller. This is probably why people who do a fresh install don't see this problem since the AMD-RAID bottom device drivers wouldn't be installed. These drivers are only supposed when setting up a raid array using the amd raidxpert utility. Otherwise for 99.9999% of regular users, the standard windows driver is sufficient.
