I admit I am not a Volcanologist but the issue as I understand it with these caldera volcanos is this isn’t simply heat but pressure... The magma contains insane amounts of pressurized gasses, so once a crack finally reaches the surface, all of that pressurized gas instantly has a route out and expands causing the massive explosion... It’s not simply oh lots of magma, forcing its way out, it’s the near instantaneous release of pressurized gasses wishing the magma finally having a route to escape.
Think of it like a water heater with the pressure release valve stuck shut, once the vessel fails all the pressurized steam has an escape route
I’m not sure how trying to steal the thermal energy via this method would lessen the gassious pressures in the magma.
Instead of a water heater leaking steam, think a pin into a ballon. Pop, it all comes out and we have an instant super volcano eruption ... NASA should stick to space.
Similar to a blowout at an oil-well.

I’m sure drilling a hole will help!!! What could go wrong??
