Motherboard wont boot to Windows 10

I have a new install, ROG STRIX X570, updated bios, installed windows 10 to M.2 1TB drive. Reset bios to defaults and made M.2 master boot.  On reboot it stops and says F1 to setup, go back to drive F8, then reboot to windows.  Question how to make switch on go straight to OS ?

Fresh Windows 10 install on this system should be an EFI boot. Try disabling CSM(Support Compatibility Module) in the BIOS under the "Boot", then save and exit. See if it boots normally.

Glad you were able to resolve it.  Are using an All in One/Custom Loop Liquid Cooling?  I have seen it where the system won't boot if the CPU_Fan was plugged in even if the PUMP was plugged in, thinking this may be the case here.
