Can defense be penalized for delay of game when stemming?

In football, a defense cannot be penalized for delay of game when stemming, as this is a common tactic used by defensive players to create confusion and align themselves before the snap. Delay of game penalties are typically called on the offense for failing to snap the ball within the allotted time. However, if the defense takes excessive time to set up, they could potentially be penalized for other infractions, such as unsportsmanlike conduct, but not specifically for delay of game.
