Just don't try putting something convenient in between, at least that's what my adventures in TB4 taught me: displayport from a TB port works fine, even when DP goes to a multiscreen daisychain and the TB does PD to the laptop on the side, but try multiscreen through a hub and all bets are off. I think it's the hubs overheating and I've seen that even on just 2x FHD (Ok, that one was on a cheap non-TB hub, but I also got two certified TB4 hub hubs to fail serving 2x "2.5k" (2560x1600). And those hubs are expensive, I believe that they all run the same Intel chipset.

How about putting the dock at the end of the chain, after the monitors, does that work?

		That would require monitors supporting daisy chain in the first place and I never had any problems with them anyways. Likely related to not using a full on hub but a minimalistic dongle with a DP outlet, a PD inlet and a USB outlet (which then goes to a USB hub switch managing access to simple hubs serving all those low bandwidth peripherals like the mouse). The failing hubs were either driving cheap office displays connected through HDMI or high resolution mobile displays connected through USB-C. Few of those support anything like daisy chaining or at least simple PD passthrough so that you can use the same port for driving the display and powering the laptop, and I absolutely do want dual mobile displays. Even if only so that I can carry them screen to screen for mutual protection of the glass.
