About Monitor connectivity of XPS 17 9700

Currently I am using my XPS 17 9700 with 2060 and with direct display enabled. I also have one lg 27gp850 running at 2k 180hz 10bit, connected via wd19tb.

I am planning to add new monitors to my future setup, either a 4k 144hz one or two more gp850s. I'm wondering if my current setup is able to handle that... Not only performance wise, but also bandwidth wise. I probably would have to connect the new monitors to the other thunderbolt ports on my XPS17 because of bandwith? Can the dock at least handle two 2k165hz 10bit Setup? If that is not the case, I will buy the monitors later on.

BTW I know it is impossible to run games at native resolution, it is only my temporary setup. I will be building a PC with at least 3070 in a year or so(so it could be 4070 then, which I am pretty sure is able to handle that much pixels hhh).
