[gentoo-user] [OFFTOPIC}: Does the MSI Tomahawk MAX is able to boot from a M2 SSD?

Hi,

maybe someone here, who owns a PC with a MSI Tomahawk MAX
motherboard can answer this question:

Is it possible to boot Linux from the installed 
M2 Nvme (or if not from a M2 SATA) SSD? ?

In the chapter about the BIOS the user manual of
the MSI Tomahaswk Max only says 
"Select Boot Priority", but does not tell about
the kind of selectable items.

Beside speed and cost:
Is there any difference between using a M2 SATA SSD
or a M2 NVMe SSD?

Does these drives are working with UEFI boot and
Legacy boot when it comes to boot Linux?

Thanks a lot in advance for any help...!
(...sorry...I went out of cryo sleep just 
a few hours ago... ;)

Cheers!
