Re: NNue variety
I see no reason why a single-threaded search using a fixed nn.bin should be non-deterministic. More than one thread should be non-deterministic. All that the nn is doing is replacing the evaluation.

Re: NNue variety
Even single thread can be somewhat variable if search is based on time.
For fixed nodes (assuming nothing the the hash tables), it should be exactly the same.

Re: NNue variety
Yes, it's exactly the same as regular Stockfish. Except for the eval ofcourse.
