If you switch before doing this, you will likely get a BSOD INACCESSIBLE_BOOT_DEVICE.
Before switch, run this as admin:
bcdedit /set safeboot minimal
Change setting in BIOS
After windows boots up, run this as admin:
bcdedit /deletevalue safeboot
Another method:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride
Change the 0 DWORD value from 3 to 0.
