Can my puppy hold it for 7.5 hours??

I’m chaperoning field trip tomorrow and have yet to find someone to come give my puppy a potty break. I’ll be gone for 7.5 hours … can my 11 week old puppy hold it that long or am I asking for an accident in his crate? He stil wakes twice a night for potty…but not sure if he needs to or it’s just a habit at this point. He has gone from 7:30- 12 without a potty break, but this would be 3 additional hours
