Can't change the m.2 from x2 to x4

[yohanio]

I just built a new PC with a NVME SSD, and I can't seem to find a way to change the m.2 from x2 to x4 in the BIOS. I go in the Onboard Devices Configuration but I don't have the option.

 

I have a Asus TUF GAMING X570-PLUS motherboard and a Intel 660p NVME SSD.

Does that even matter? PCIe 3.0 2x is still 2GB/s - the 660p tops out at 1.5GB/s sequential read speeds in ideal perfect factory controlled conditions.
