4 - Click on key management and clear secure boot keys.

6 - Press F10 to save, exit and reboot.
7 - Windows 10 will now start installing to your NVME drive as it has its own NVME driver built in.
8 - When the PC reboots hit F2 to go back into the BIOS, you will see under boot priority that Windows boot manager now lists your NVME drive.
9 - Click on secure boot again but now set it to WIndows UEFI mode. (see #3 above)
10 - Click on key management and install default secure boot keys
11 - Press F10 to save and exit and Windows will finish the install. Once you have Windows up and running, shutdown the PC and reconnect your other SATA drives.
