   The only non-X570 Asrock board with add-on Thunderbolt support appears to be B550 PG Riptide.

You'll then need to add an Asrock Thunderbolt 4 AIC card.

To get DP Alt-Mode working, you'll need to connect displayport output from the GPU (or I guess motherboard if using iGPU) to the Thunderbolt 4 AIC card.

	Hello, I am looking to build an AM4 system, preferably ITX but I am open to slightly larger platform too. I know that the X570 ITX has Thunderbolt 3 ports, so I can get USB-c with DisplayPort AltMode via this port, but I don't want an X570 board. So, is there any other AM4 board with USB-C AltMode enabled/supported?
