No.

There are no spheres, only circumstellar device clouds, with actively
controlled orbits.

You need a circumsolar device in order to at all to touch the star. Darwin drives for
maximum habitat, that is, computation/Joule (signalling is relativistically
constrained here, though). It depends on matter/energy ratio in the system. Ours seem to
have enough matter to intercept all solar output, and even to put it all to
good use.
Maybe shutting the star down, and going for a slower burn might be more
effective. Maybe not.
