XPS 13 Plus 9320 - Ubuntu/Linux and Thunderbolt dock + dual 4k Displays

Hi!

Im recently got a Dell XPS 13 plus 9320 for work. Its an amazing laptop, but I wish to run it with Ubuntu.

The problem here is that it only has 2 thunderbolt ports and I havent been able to get both my 4k monitors to work over Thunderbolt 4 with it.

My setup is as follows:
Dell XPS 13 9320 laptop
Lenovo Thunderbolt 4 Universal dock
2x Samsung LS32A80 4K 60hz Monitors (As far as I can tell they support HBR 1.1 and 1.2 only)

Ive read many threads about this, but none of them seemingly answers the question: Has anyone been able to run dual 4k monitors over Thunderbolt on this machine? Preferably at 60hz
And if anyones got it working.. whats your setup? What should I change to make it work?

Im currently running it with Windows 11 and everything is perfect, but working with yarn/npm and python both locally and in Docker containers over WSL2 is a pain with how Windows works, so would love to revert to Ubuntu / a linux distro. 

Edit: Should also mention that as for settings change and so on, I havent changed anything. After testing it with Ubuntu I reformatted it to Windows. Bios settings is defaults all the way.
