I'm not sure that the problem is related to CPU type. It's more likely related to DMA Controller (DMAC). My 2020 13" MacBook Pro also has a properly defined DMAC device in DSDT, and both AppleVTD and DMAC appear in IOReg.Is it possible to spoof one of the 2066 socket processors from the x299 boards?
Is it possible to patch the Big Sur kernel? I suspect VT-d is somewhat widely used, which means kernel patching might not be viable. But this is just speculation.
