You can buy add-in cards that do lane bifurcation

E.g. https://www.ebay.co.uk/itm/126656188922

Most motherboards don’t go beyond 2x8 with 2x16 physical slots because there is little actual use for it and it costs quite a bit of money.

Bifurcation is done on the CPU.

Asus 5.0 Hyper M.2 with yield 4x4x4x4 in a board that is setup for bifurcation of PCIE slot 1 like that.

I have run 4 GPUs this way and it works very well.
