Loading the manual pdf on the asrock site for this board and searching for IOMMU shows an bios entry under AMD CBS for that.
Depending on the bios version, the exact menu position can vary.

Dear LordPlaybot,

Greetings, this is ASRock TSD.


B450M Pro4 supports IOMMU function.
Please refer to the following path to enable it under BIOS setup.
BIOS\Advanced\AMD CBS\NBIO Common Options\NB Configuration\IOMMU


Thanks!

All the best,
ASRock TSD
