MSI B550M MAG Mortar BIOS mod

The second pcie 16x slot on this board is disabled if you populate the second M.2 SSD slot. Is it possible at all to mod it so that you can use both? I only want to install a network card in the second slot, not a graphics card

The reason you can’t use both at the same time is because they supposedly use the same pcie lines to connect to the cpu. However I believe the second nvme and pcie 16x which I believe is actually only an 8x wired 16x sized slot. I know crap right. But how I got around the situation was to buy a pci to nvme adapter. So I put my nvme card into the adapter and installed it in the 1x slot between the two 16x ones and am able to use both. And why don’t you just install the network card in the bottom pcie 1x slot?? Or just in the one between the two 16x pcie’s
