Does anyone know if the MSI Pro B660M-A Wifi has good IOMMU groups for Linux passthrough gaming?

do you need to enable IOMMU on intel motherboards, or intel vt-d?
you should find it in BIOS/ OC/ CPU Features

good IOMMU group? if you're saying 2 PCIe slot can be split to 2 different IOMMU group, that shouldn't be a problem especially when one is from CPU and the other one is from chipset.
Make sure you edit and upate the grub file as following though,
GRUB_CMDLINE_LINUX_DEFAULT="iommu=1 intel_iommu=on"
