Setup Suggestions for Macbook Pro/Desktop PC Dual Monitor Sharing

[Tech_spec]

Hi everyone. I have a specific setup that I was looking to achieve, but it seems harder than i thought given the hardware I have. Just looking for any suggestions anyone might have on how to make it work. So here's the devices involved in the setup.

1. 2018 Macbook Pro 15 Inch w/ Touch Bar and 3 available USB-C ports
2. A Desktop PC with an HDMI port and a DisplayPort
3. 2 x 1080p monitors, each with one HDMI port and one DisplayPort

So i'm looking to be able to hook the macbook up to the monitors for display extension, as well as hook my desktop PC to the monitors. However, i'd like to be able to get a Thunderbolt 4 dock as well (one that's compatible with M1 chipset preferably for future upgrades) to only need one cable to hook up to the macbook to ultimately send video to the displays and get power.

Trying to find the right dock and cables is turning out to be a pain. I'm hearing that some cables need to be active while others don't. A lot of docks don't seem to support the M1 macbook pros, docks need DP Alt mode to be able to support some cables, etc.

There just seems to be too many variables for the specific setup i'm aiming for an it's frustrating. Can anybody provide any suggestions on docks and cables that may be able to fit the setup i'm looking for?
