Can't enable Ultrafast Boot in the BIOS, can't disable CSM in Boot
I have just finished installing everything on my new system and realized that I can't enable Ultrafast Boot in the BIOS. Every time I enable it, it reverts to disabled.
I'm using an NVM.e m.2 SSD (SK Hynix P31 Gold 1TB). Everything was set to UEFI during the installation process, but I did not have CSM disabled before I installed the operating system, which is Windows 10 Pro 64-bit. I think perhaps part of the problem was that I used a very old graphics card during the installation (nVidia 9800GT), as my processor has no integrated graphics, and I had not yet moved my normal GPU into my new system. But I was able to navigate the UEFI BIOS during the initial BIOS check, so that's probably not it.
Now I have my more recent GPU attached and trying to enable UltraFast Boot in the ASRock Z590 Steel Legend 6E WiFi motherboard, but it's not working. Trying to disable CSM doesn't work--it keeps auto-reverting to enabled. Although CSM is effectively disabled, since "Launch Storage OpROM Policy" setting is UEFI Only.
Trying to enable Ultrafast Boot doesn't work: it keeps auto-reverting to disabled.
For reference, I'm using that m.2 SSD as my main drive and 1 WD Black 6TB WD6001FZWX storage HDD. I did not have the HDD connected when I did the Windows install--only the SSD.
Isn't there Anything I can do about this without doing a complete reinstall? I've now installed so much software with activation codes, it's a major headache to do a complete reinstall.
