Ubuntu 20.04 freeze on any display changes or unplugging external display

I have the same situation. My docking station works perfectly on Windows. The problem is the same as described in the posts above on several distributions. I am currently running Mint, but also tried it on ubuntu and pop.
If I start the laptop with displaylink device and monitors attached it won't boot, it waits on blank empty screen (not even Ctrl + Alt + F1 works).
Power button is the only solution. The same happens if I unplug the dock when monitors are connected although in this case the laptop screen keeps the last picture it had before unpluging the dock...

I also noticed that the computer freezes when I try to change the order of my screens, after clicking apply the computer freezes. This only happens on NVIDIA drivers (460, 470, 495 beta) if I use nouveau opensource drivers everything works fine, but the performance is less then fine

I am currently running on 5.13 kernel but also tried 5.15 and many in between.

My computer:
XMG neo 17
Ryzen 9 5900HX
Nvidia GTX 3070

I hope this is fixed in the near future because I am loosing my mind over it... looking to switch to windows in meantime...
