I have the Belkin TB-3 Dock Pro (F4U097) and have had moderate success on EndeavourOS (FW 13 AMD 7840U):
- Charging works fine
- DisplayPort works fine
- Ethernet works fine
- None of the USB-A ports seem to work
- Audio doesn’t seem to work
- Can’t use the 2nd TB3/USB-C port for a monitor (the monitor is recognised, but linux can’t detect the resolutions so it’s stuck at 800x600), at least not with my USB-C > DP/HDMI cable that I previously used with my MBP
Edit: I meant 640x480, not 800x600
