Nvme for Sabertooth 990FX R2.0/GEN3

[NekoKo]

Hi

please I need help.

I would like to upgrade bios 2901 on Sabertooth 990FX rev2/GEN3 (limited edition) motherboard, but I'm a little confused about that because on the official Asus website for Sabertooth 990FX rev2/GEN3 (limited ediotion) exist only 2501 bios version, but for Sabertooth 990FX rev2 exixst both update files 2501 and 2901.? Theese two mottherboards are very similar.

The reason I would do it because bios version 2901 have Nvme support and Sabertooth gen3 have PCI express 3.0 (ideal for samsung 960 pro via PCIe/m2 adapter).  

If that is not possible can I insert modules (Nvme, NVMEINT13 and NvmeSmm) from Sabertooth 990FX rev2 bios 2901 to bios 2501 of Sabertooth 990FX rev2/GEN3?

Sincerely
