I'm not sure I understand your question - the monitor is connected through the TB port. If I remove the dock, the monitor won't receive any signal.
The situation is as follows:
Only one receives a signal when both monitors are connected to the dock.
If I disconnect one of the monitors, the other one springs into action.
They both work if I connect one monitor via the dock and one via the laptop's HDMI port.
When I used the Dell PC, both monitors worked when connected via the dock, so I know the dock's connections are not the problem. Other than that, I'm clueless
I had the same exact issue, and I found a workaround, which isn't elegant, but it works.
I took the TB16's USB-C connector and inserted it into USB-C port nearest to the back of the laptop. This port looks like a standard port. This allowed the wired internet and video to go through to the T480, and it also charges the battery.
So, not sure about your video issues, but I use two Acer ET322QU Abmiprx monitors connected via DisplayPort, and not having an issue (other than the fact that the T480 which I have does not have the power to output to x1440, so I only get x1080. But, eh, it's for work). Have you tried connecting the troubled monitor directly to the laptop's HDMI port? Again, not elegant, but it may work.
To address the USB hub issue, I took a separate USB-C travel hub (one of those you can buy at Amazon or Best Buy), and connected it to the USB-C port that's part of the Lenovo dock connection. This is adjacent to the port described above, and this second port shares space with what looks to be another proprietary connection for Lenovos. It doesn't look like a USB-C port, but it is. Doing this allowed me to use my USB keyboard/mouse with the T480. (BTW, I use the USB-C hub device with my regular setup that includes my Dell laptop because the TB16 didn't have enough USB ports for me, so it may be a good investment for you too, if you use a lot of USB ports.)
I didn't have to install any drivers or anything to make this setup work. However, depending on the admin settings, your newly connected USB devices may need drivers, etc. to function at their maximum.

I added photos for reference. Hope this helps.
