I recently wanted to do this and was surprised to learn that USB3 did not have a point-to-point mode like thunderbolt - some controllers had "dual mode" ability but the vast majority don't. I was doing this on Macs with thunderbolts 10 years ago but still couldn't do it on a PC today.

Despite being great in most ways, AMD desktop systems in general rarely have thunderbolt (unlike Intel) - a few niche motherboards have it. You also can't just add it with a PCIe card, it requires special support from the motherboard.

Hopefully this might change with USB4 not sure.. be interesting to see what the lower end motherboards end up shipping support for.
