Hmm, this has me thinking about the stealth ships in The Expanse. The engineering needed to make it work makes me want to cry, but in principle you could run a Peltier cooler with a swappable heat sink.
To be clear, I don’t think this is a viable option, but it’s interesting to think about.
Basically the way you would make a stealth spaceship would be by focusing as much as possible on energy efficiency. At every juncture you would try to use as little power as possible, and use every bit of it as efficiently as possible, so that you’re not remitting waste. That waste, in the form of heat, radio waves, etc, is what gets you spotted.
You could also run heatsinks temporarily for enhanced stealth as you suggest, then open up radiators to cool them - or eject them - once it’s safe to do so.
(For the Elite: Dangerous players, yes, that game got it right.)
