@Youcandothis , billions of computer engines games are already played, there is no single game where one side win without mistake from the other side.
If you ask this question among, computer engines testers , they will laugh you and assume you as if the person who dont believe "the earth is a sphere etc".
In fact, if you look at stockfish programming forums, you can see 1000-1300 rated programmers can find out 3600+ stockfish mistakes by looking at reverse analysis. As they know that chess is draw, whenever they see a game where Stockfish lose, for example, at move 40, they let stockfish analyse from move 40 to 39, 38, 35 etc.
It is quite similar to telling stockfish, you know you did a mistake, you depart from theoretical 0.00 at move 1 to 0.00 at move 40. , which move you depart from?
