Thinkpad X390 doesn't detect Thunderbolt 3 dock (belkin)

Hi,

i have a Lenovo Thinkpad X390 and from work a Thunderbolt 3 Express Dock HD (belkin).

Whatever i try, i can't find it with boltcli or in other ways as thunderbolt device i only find it as low-speed USB.

dmesg

What i tried so far:

- configured bios to disable kernel dma, configured thunderbolt to use user security and disabled thunderbolt on boot auto auth?
- tried boltctl, just no other device ever popped up
- added udev rule to allow thunderbolt device
- updated bios/uefi to newest (march 2021)
- modprobed thunderbolt and intel-wmi-thunderbolt -> no issues/no error messages

I'm not sure what to test further and i find it weird that the docking station doesn't show up as anything else; I do understand it is primarily a Macbook docking station but it could work or should show more?

Tx for your help.
