The initial position is from a study by N.Elkies and it shows that you cannot trust stockfish to handle the 50 move correctly and that it even can show false mate scores.
Note that I used 3 cores and stockfish is not deterministic with 3 cores so it can show also 0.00 but basically you cannot trust mate scores of stockfish to be correct.
Note that I am not convinced that the study is correct and maybe black can win faster without a draw by the 50 move rule but unfortunately I know no engine that can help to prove that the study is correct and if I cannot trust even mate scores then mate score in some different line also prove nothing.
I did not find a way to progress faster and force a win but not finding a faster way is not a proof because maybe there is something that I missed.
single core , 2048M hash, 7 men syzygy, and the output below is deteminsitic with the aforementioned settings
