Perfect, thanks!

But also I see there is a linux driver available for download from the 
Supermicro website. Is it possible to make driver changes and talk to 
both nvme disks without bifurcating a pci-e slot?

For future reference the knob is under:

     Advanced -> PCIe/PCI/PnP -> CPU SLOT{1,6} PCI-e ... bifurcation

I had to do testing with a different motherboard (X10DRW-i) and even 
after updating the bios wasn't able to find the magic option to boot 
from a nvme. The manual says:

     change the Device Option Rom Configure "UEFI mode" from Legacy

but this didn't give me any nvme drives to configure to boot from.
