Hmm, how to do that? Dump some kind of moderator material into the core? Amplify some of the acoustic modes so that a pressure wave destabilizes the core?

Maybe dropping one or more small black holes into an orbit through the core region might do the trick. It should cause some mixing beside the local heating, parhaps delaying the collapse a while as there was other stuff to burn.

Could work, but the problem might be handling the relative differences in speed between an incoming and an outgoing star in an eccentric orbit - a deltavee on the order of a few tens of km/s for a gas giant is rather heavy. And doing wild things like stellar atmospheric braking while carrying around a terrestrial planet is not adviced, it might break.
