Whick docking station is used ?
(For the record, I have a P15Gen2 + TB4 Workstation docking station)
This is exactly my setup
I would suggest to open a bug for each different issue, since they touched various parts of the OS (or systems).
Networking not working might be a bug in Lenovo firmware, see https://github.com/fwupd/firmware-lenovo/issues/191#issuecomment-1094253562
Firmware updated tonight using Windows - screenshots attached.
For GNOME, it is used under Wayland or Xorg ?
Xorg - Wayland is a failed experiment for me with more drawbacks than value.
There is still issue when using Wayland and nvidia driver, in hybrid display mode: https://gitlab.gnome.org/GNOME/mutter/-/issues/2166
Try to turn off hybrid display in Firmware setting. For me, it fixes most of the issues (still some issues with suspend.
System Settings have been only discrete graphics from day one.
It looks like it is recognized by the OS:

As soon as I plug in the network cable, it kernel panics.
