Couldn't it be a good emitter, but redirect the heat in a focused way? (beam of RF)

The sibling already mentioned the axioms of thermodynamics that forbid it. Another way to see that this is forbidden is Etendue https://en.wikipedia.org/wiki/Etendue#Conservation_of_etendu...

Any thoughts on this? (discussion on temperature of a black hole)

Nope. That would violate the 2nd Law of Thermodynamics.

Why?
Couldn’t one build a dyson sphere around a blackhole? Wouldn’t the blackhole have properties of a Bose–Einstein condensate given the matter at the center cannot vibrate?
It would be the coldest temperature possible. Heat moves downhill, you deposit heat into a singularity and have a shell around it.
That aside, at even a scale of a single dyson sphere, something tells me when a civilization has the power to bend spacetime, the rules of possibilities begin to change. I think it is unwise to operate with so much certainty in the face of possibilities.
