All four ports support Thunderbolt 4 - if you scroll down to "Interfaces" on the product specs page there's a graphic showing everything that's supported.

nice! Thanks! I had no idea USB4 and Thunderbolt were equivalent.

They aren't equivalent. The "shape" of the port is the same, it's (USB) Type-C. Though as far as I know most of the time you can use USB4 peripherals with TB4 ports.

They do a terrible job with the documentation... making TB4 (superior) sound like it is USB-C (3.2 or something?). Only the Intel versions seem to support Thunderbolt, the AMD not which I think is the main issue.

Anyway, the next Frameworks need to adopt Thunderbolt 5 to handle modern HDMI 2.1 and 2.2, eGPU, Oculink, etc.
