So the link above and my step by step below is here for completeness.

Nothing else and that also did the trick, just like with moving from RAID to AHCI. Turn off safe mode and reboot normally again.I have also tried the same process used to switch from RAD to AHCI and that works as well. This works with both SATA SSD and M.2 NVMe drives and it enables relatively fast switching between back and forth between AHCI and RAID. I have described this method below. Manipulating some registry settings in combination with a safe boot before booting normally does the trick as well. I personally have used other ways to do this. Make sure you read and understand it before jumping in. You can also find a procedure to move from RAID to AHCI in. Depending on your approach it can be a more tedious process with some risk, but normally you can always fall back to AHCI if it doesn’t work out and, otionally, try another approch. If, however, you want to move back from AHCI to RAID when newer drivers become available this is also possible. With my NVME disk, I have not seen a huge performance difference between AHCI with the native Windows driver and RAID with Intel RST. Moving from AHCI to RAID can also be achieved without reinstalling Windows. In the previous blog post, we moved from RAID to AHCI.
