Welcome to the forum!!
Odds are if there isn’t a powered fan in the vent hole, there isn’t 12V run to it. That said, getting 12V to it may be a simple or complicated task. If there is a light nearby you can tap into it. But if that light is on a wall switch it would mean the light has to be turned on. It’s common to run 12V wiring in the rafters and if you take the inside vent part ( garnish ring) you may locate some wiring. I’m pretty much all RVs the 12V wiring is stranded wiring with two conductors. White is ground and white with a colored tracer is positive. I have a test light that I can pierce the wire to see if it’s “hot”.
You might be able to fish the needed wirebover to the stove vent or refer via the rafters. Where there is a will there is a way.
