I was able to plug into the remaining HDMI port of my computer's GPU using an adapter cable I got from Amazon: WJESOG HDMI to USB C Cable 6.6ft 4K@60Hz with USB Power Adapter and a USB-C female to female coupler adapter.
I use these:
AINOPE USB C to USB C Cable, [100W 6FT 90 Degree

Plug your ethernet cable into the adapter and you are on your way. Plug your charger into the ethernet adapter. Make sure the usb setting is @ "transfer data" in the developer tab.
Try this thunderbolt 3 female to female adapter. Much cheaper than buying a dock
This is that I use to charge with a ethernet hub my pico 4.
