Can a D-I football game end in a tie?

So in my football pool I'd like to pick Notre Dame-Michigan to end in a tie. Both teams suck so hard neither deserves to win, but it occured to me that with the overtime rules, can a game even end in a tie?
I know that at the third OT, you have to go for two-points if you score a touchdown, but what if neither team scores, would they call it at the end of the third OT, or would they keep playing until someone scored?
Is it different for non-conference games?
Does anyone know ...

 

It can't end in a tie.

 

No NCAA or NAIA game at any level can end in the tie. All levels use the same overtime rules.

 

Double forfeit, if both teams are ultimately found guilty of NCAA violations?

If the winner is stripped of the victory but the loser is also put on probation? Hey, Oklahoma probably played somebody else last year who was cheating.

 

Nope, unfortunately one team has to win. I can still hope for 19 turnovers, though.
