Again , this is an interesting position I need help to solve. In a game Stockfish vs Ethereal , Stockfish was ahead , but Ethereal could have found refuge in the following endgame. Is the position winning for White anyway? Could Black steer it into a positional draw?
[White "Stockfish"]
[Black "Ethereal"]
[FEN "4b3/4N1k1/3R3p/r7/8/P6P/5KP1/8 b - - 0 1"]
I am unsure what version of Stockfish you were using so I ran analysis 12 times; 4 seperate engines for each version of Stockfish.
Results were Stockfish (white) at the end of 20+ moves, was in a stronger position in all 9 instances. Based off this, I would suggest black is in a losing and in a irrecoverable position. There is the potential for a draw but it appears extremely unlikely.
The best variation / playout that I saw, that had the best end position for black, was Stockfish 12 vs Stockfish 12. +-3.03 / 41 so white is decisively better.
Issue with engine games in these sort of positions are the gameplay is boring. That being said, I have attached it for reference though.

From my experience with engine games this is going to continue on for some time. Eventually the Black h pawn and Whites a pawns will go (will likely also involve trading out the bishops somewhere ) , white with the pawn advantage will promote.
this would be tough to win OTB with many ways to end up drawn
a computer might do it but I doubt it would be quick and easy
