Probably so.
The powers that be at Fox, don’t want to be seen as blatantly partisan, or obstructionist, or sore loser types.
The powers that be at Fox, looking ahead to a Democrat administration, want to be in the good graces of said Democrat administration.
If Fox simply called balls and strikes fairly instead of declaring winners before the end of the ninth inning (if there even is one), they needn’t worry about their image.
