Is it possible to disable the popups in certain gmaps?

we have a small map in a sideblock that shows the location of the node you're viewing. Since you're already looking at the node, there's no point in having the popup in the gmap. We'd like to eliminate it entirely. Is it possible to do this?

I would imagine I could set its size via CSS to something really tiny, but I'd rather disable the pop-up entirely if possible. We don't want to do this globally, because we use gmaps in an other location where we do want the bubble to point you to these nodes.

Is this possible? if so, how?
