I was wondering this as well. I don't have such a cable, but I am thinking it might work. The USB C connector on the dock looks like it just feeds right into the hdmi cable.

There isn't much info online about this. Just old forum posts.

Reddit seems to think there's a lockout chip in the handheld that prevents you from using anything but the dock to connect to a tv.

Maybe you could rip open the base (it seems it's only plastic), do a little work and get back the power/hdmi/usb c converter inside it.
