The NVMe-RAID is connected to a Downstream-Switchport for PCIe. If the NVMe-RAID-Drivers are known to Windows, but the RAID was not explicitely installed, an NVMe-Disk will be connected to an AMD-RAID Bottom Device connected to the Downstream-Switchport. Now, this disk is invisible to Windows since the Bottom device would be accessed through the RAID device, that is missing. This disk is also invisible to RAIDXpert since RAIDXpert would access it by a AMD-RAID Config Device next to it. The problematic Bottom Device remains active, blocking the access to the NVMe disk, no matter how the NVMe-RAID-mode-Switch is set in the UEFI.

The Bottom device needs to be deinstalled manually.
Invisible NVMe

|> NVMe_DISK
Restart into SAFEBOOT MINIMAL, remove the Bottom device and install the AMD-RAID drivers provided by download or the respective UEFI tool.
P.S. The init as a RIAD device whipes out all data and any disk connected to a RAID-Controller needs an init. This also concerns the use as a JBOD on a RAID-Controller, i.e. usage as an independent disk. Thus it's always a good idea to init any disk connected to the system, unless you're sure that you'd never change to RAID use.

When installing Windows, the different drives of the RAID array are shown as individual drives.
It is important to load these 3 drivers in the correct sequence.
After that the Array is shown.
1. Rcbottom
2 Rccfg
3 RcRAID
This should also be in the RAID manual on the ASRock website.
These drivers are either in the download for this board

Called SATA Floppy Image (no idea why, since floppy, is ancient history), or you van go to the download on the AMD website, seelcvt the chipset, and you will also find RAID drivers, and Raidexpert software there
