Just to avoid an xy-problem, could you please add a sentence or two explaining why you want to do this?

There could be a perfectly valid reason, but it would be good if you could tell us about your motivation.

I'm writing a publisher node to publish camera image data on a topic, now if i unplug the camera, i want to stop that topic from being advertised.
