NVMe found in BIOS but not by Windows 10 / Windows 11
.......

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.
