List of pre X570 motherboards with PCIe 4 enabled on Ryzen 3000 through BIOS updates

[Shmee]

Not sure if there are any BIOS updates out yet which will bring PCIe 4 to X470 and the like, but I figured I would make a thread here so that when we get these BIOS files for boards we can post links, whether they are official releases or modded BIOS files. I will try to update the OP as needed.
