Hi

I have Fatal1ty B450 Gaming-ITX/ac with ryzen 2700. After updating bios to version 3.70 I cannot find the IOMMU -setting. I have combed through all the menus and seems like the setting simply is not there. I cannot downgrade bios because the earlier versions have other stuff broken.

Should the iommu setting be there at all? Do I have to flip some other settings before it appears? Do I have to upgrade my cpu to 3-series to make it work?
