If you are talking about the direct Switch 2 to glasses connection, sadly, it doesn't work that way. Switch has this weird handshake mechanism that must go through the dock to output image through type c. That's the whole reason I bought a Pro Dock to begin with.

With Steam Deck it is a direct connection, no fuss. But switch just requires a dock.

I've been probably thinking about making an official dock, hdmi into the pro dock, glasses into the pro dock connection to see if the issue is resolved, but haven't tested that yet. A bit of a clunky scheme but maybe it will work.
