If I were going to try an influence an election via voting machine software, I would affect only some percentage of votes so it wouldn't be too obvious--if there was also mail in ballots, it wouldn't matter. I might also target only key locations--those on the margins where it wouldn't be suspicious. If I were to do this in favor of the Republican candidate, you'd probably find that mail-in votes even in non-pandemic years skewed more Democratic. You'd also find that polls seemed to indicate that Republican voters were "shy" and it keeps messing up the polls.
