Speaking as someone who's generally willing to consider beyond-the- horizon technologies (asteroid capture for example) I have to say I see no way we could plausibly trigger an eruption. The sheer amount of rock rules out simple removal, and likewise any in-situ modification of the whole mass of rock. Making cracks would be something that affects only a small portion of the rock, but it isn't a solution: some magma follows cracks, but cracks aren't a limiting factor.
