trying to find an AM4 motherboard with good iommu groups

[BenCos18]

got burned already with a b550 motherboard not having any proper iommu groups and crashing promox when I passed through the hba to truenas
currently I have an asrock b550m pro4 with a ryzen 7 5700g

ideally it needs two pcie x8 slots for my hba and the 10gb nic I'm planning on adding
microatx also as the server case I use only supports that size
ideally around 150 budget but I can try and stretch to 170 if need be.

thanks

As discussed many times before on this forum (when AM4 was still the latest): only X570(S) has almost everything in separate IOMMU groups. X370 and X470 has 2 times x16 PCIe (working as x8) and 1 M.2 slot. X320, X350, X450, X520 and X550 has one x16 PCIe and one M.2 slot, if I remember correctly.
