Passing through Thunderbolt 3 (Titan ridge) controller

[Emma]

Hello helpful soul,

I've been trying make the vm i use day to day better step by step.

Currently I'm trying to get a usb(or thunderbolt 3) controller passed through to the windows 10 VM.

I have a gigabyte z490 vision D which has integrated thunderbolt 3 ports, since it would save me a pci-e slot I'm trying to pass this controller through to a vm but i cant seem to get it working. Does anyone know if this is even possible? and if it is, some tips that could get it working?
