@Jason_Hilton One way to solve this would be to avoid HDMI

There are DSI to eDP ICs on the market. Retail IC price seems to be close to $20 though.
Add a PCIe switch for nvme and usb3 and those would be set, too.

The next hard part would be USB-C. You would need to find a way to mux HDMI, PCIe, Power & USB3 to the ports. Not sure what ICs to look at for that… Especially only 2 HDMI outs could be problematic. 4 port USB3 shouldn’t be an issue, and there are 5 port PCIe switches, so 4 + nvme would work…
