Physics Question: Inducing Novas

I've got a really strange (astro)physics question. Given sufficiently
advanced technology, is there a way to induce "the average star"
to go nova within a relatively short (hours, days) period of
time? If so, what sort of manipulation would be required,
and what sciences would have to be developed in order for this
technology to become available (i.e. what TL are we talking)?

Apologies in advance if this is an old topic.
