Is there a 10 second run off for offensive penalties at the end of games?

Last night with the clock running and about 1:29 left in the game on a 4th and 3 Texas committed a false start. There was no 10 second run off and the clock did not restart once when the play was replayed at 4th and 8. Is this a rule that’s only in the NFL and I’m getting the two confused?
