Some x470 boards support it to via an addin card and thunderbolt header. To get displayport passed through you need to run a cable from your graphics card output to the addin card input. It's not very tidy and doesn't work 100%.
I'm hoping someone eventually just does the needful and sticks a thunderbolt chipset on a PCIE4 graphics card and makes it work somehow.
