Per The Athletic:
"Penn State has the White Out. Tennessee has the checkerboard. Boise State has the Stripe Out. Even the Texas A&M red, white and blue crowd after 9/11 is in the game — I’m not sure how that one activates, but special crowd colors will happen for the biggest games in Dynasty mode. We were told some teams have called EA Sports to let them know of crowd blackout plans later this season to be included in the game."
Might be us. Not sure what other teams do it.
