Hardware Support questions

Can anyone point me to a list of supported motherboards ? I'm building a new PC and looking either the Asus z790 Maximus Hero or the Asus z90 Maximus Formula motherboards but I'm having trouble confirming that these motherboards are supported. Anybody using Tumbleweed on one of those motherboards ? Those boards have an HDMI port and 2 Thunderbolt 4 ports and the Thunderbolt 4 ports support DisplayPort over Thunderbort 4. I have a dual 27" monitor setup with one of the monitors using DisplayPort currently and was planning to get a DisplayPort to Thunderbolt 4 cable. Does anyone know if that is supported ? Thanks in advance!
