It sounds like the dock and the number of monitors are the two main
issues.

* Your laptop's USB-C port only supports DP1.4, so is limited to HBR3
which can drive the Samsung G9 at 120Hz true colour (or 97Hz in deep
colour/HDR) under ideal conditions with a perfect cable, but will have
no additional bandwidth to drive the second monitor (unless you limit
both of them to 60Hz).

* USB-C docks reduce the signal quality, so expect lower capabilities
than just plugging directly into the laptop. Also I've had bad
experience with Ugreen display cables myself recently.

Basically I think you need to eliminate one monitor or the dock itself.
It looks like the laptop has a lot of spare bandwidth on its own HDMI
port so I would consider plugging one monitor into that instead. If you
do that then you might be able to keep the dock.
