P9X79 PRO BIOS to boot off Samsung 950 PRO NVMe drive (on a pcie card)

Hi, has anyone been able to do this and would be willing to share the steps? My board is currently on 4801 and it does not see the drive as a bootable device. Windows 10 sees it as a drive once booted, but I cannot boot from the NVMe device.

Thank you! Hammer
