If the first PCIe lane has a 4.0 GPU and the second has a 3.0 GPU, what happens during the split?

You're considering a 6900XT or 6800XT with your GTX 1060 6GB for VM passthrough. Bifurcation will determine how the PCIe lanes are assigned—whether both slots run on PCIe 3.0 or if you can swap them to use PCIe 4.0 at the top and 3.0 at the bottom (or vice versa). Your current Gigabyte X570S Aorus Master setup will need adjusting based on the chosen configuration.
Additionally considering the same question about setting up a PCIE 3.0 NVMe SSD in the slot linked to the CPU, not the motherboard chipset.
I was curious about the same issue since I need a PCIe 4.0 graphics card and an PCIe 3.0 x8 I/O card that works with my ASUS ProArt Z690-CREATOR WIFI motherboard. According to the details, it should support PCIe 5.0/4.0/3.0 at x16 or x8/x8. I've seen posts suggesting each card can adjust its lane speed separately: https://superuser.com/a/1116605 and https://hardforum.com/threads/pcie-bifur...1044880646
