I'm able to passthrough two 2080TIs, and also 3 M.2 NVME drives.  The only tricky part was determining their order to match with the nodes on my AMD cpu.   My machine has no primary video card as well.

Cool.  Can you tell me what you mean by: determining their order to match with the nodes ?

On my threadripper 2950X (being replaced by a 3970X picked up on Craigslist for what must have been something as drastic as a divorce) the two 'halves' of the CPU (so cores 0-15, and 16-31) communicate directly with different PCI-e slots and devices.  So for best performance it's best to pair a passed-through device with a VM utilizing the cores with the direct connection.  This varies with CPU types however.
