Dual monitor setup with Lenovo Thinkpad P1 and Lenovo Thunderbolt 3 Dock (Gen. 2) - Troubleshooting

Hi,
after about a year of running Manjaro XFCE on my Desktop system and two monitors directly connected to the graphics card I also wanted to transition my work notebook to Manjaro. Currently I am running Manjaro 21.0 with a 5.10 linux kernel.

The laptop is a Lenovo Thinkpad P2 Gen. 2 with a Intel i9 with integrated graphics and a dedicated Nvidia Quadro T2000 graphics card.

I am using two 1920x1200@60Hz monitors. With a windows system everything is working and being displayed correctly on both displays.
After connecting the Thunderbolt 3 dock to the notebook with Manjaro everything but the displays is working flawlessly.

Both screens are detected and show up in xrandr and the display manager.
Unfortunately if I have both screens connected they stay black and cycle through sleep mode and black screen within a few seconds without actually showing anything.
If I only connect one screen it works without a problem.
If I downscale the resolution of both displays it again works, but distorted.

I have searched through the forums, reddit and google for a couple of days now only finding similar problems without working solutions, so I thought I just throw the question in here and see if anybody has had similar problems and might point me in the right direction.

System information (without dock as I am not at home):
