eGPUs won't help at all there. If your chipset and CPU support IOMMU virtualization (generally any Skylake+ or Ryzen CPU will, chipsets tend to vary more) then you can already do it with your internal discrete GPU, otherwise those will block it anyway.
However, even then the GPU's PCIe slot will need to be in a separate IOMMU group (generally only the case if it is connected directly to the CPU, bypassing the chipset, usually the case for 1-2 slots per mobo at most), which I strongly doubt Thunderbolt slots would be prioritized for.
