What Z690 Motherboards Support Iommu groups well?

I’m looking to buy a new motherboard and processor, and I plan on doing GPU passthrough so two people can both game at one time. I was thinking a 12900k might be a good choice, but I can’t seem to find information on how well they Iommu groups which is a requirement for GPU passthrough to my understanding. I know previous Intell motherboards have not supported this feature. Are there any Intell motherboards that support this with the latest generation of processors or am I forced to buy AMD?

I would like the same information
