AMD has reportedly put the hammer down on manufacturers who insist on adding PCIe 4.0 to older motherboards. The latest AGESA Combo release, AM4 1.0.0.3 ABB, removes that support for non-X570 motherboards.

GIGABYTE’s latest BIOS changelogs for the GA-A320M-H and X470 AORUS GAMING 7 WIFI confirm this. While the regression is sure to anger some, the update does fix the boot issues for Destiny 2 and certain Linux distributions in Ryzen 3000 systems. It also improves XMP DDR compatibility.

AMD announced before the launch of Ryzen 3000 and the X570 platform to understand that you will make PCI-E 4.0 only available on X570 motherboards. The motherboard manufacturers, however, wanted to upgrade their product portfolio on their own.
