Anyone know if their machine config can scale to do hydrogen-boron fusion at a later stage?

No, I don't believe that works.

I took a brief dive, and have to admit that I think your conclusion was right.

p-11B fusion is really hard. Fortunately, the folks at Helion have found ways to greatly reduce the DT neutron production in their reactors. They still will have neutrons from DD reactions, but those neutrons are much less damaging due to their lower energy.
