On this dock I have two monitors connected. One is connected to the display port of the dock, the second one is connected to an USB-C Thunderbolt port using an USB-C to mini DP adapter. The second monitor is only detected, when I _first_ plug in the adapter and _then_ plug in the the cable to the adapter. This also only works when the system has booted _and_ I am logged in. I already disabled thunderbolt security completely in UEFI. Once the monitor has been detected it is also working during boot, when I restart the system.
