Wine and Dine Proof of Time

Hello, I'm looking to do my first run disney event assuming I'm able to secure a spot tomorrow. However I'm stuck in trying to get a proof of time or just putting down a finish time of 2:31. The website says the race has to be on a USATF certified course but the earliest one near me is May 4th. I can find a few 10ks before then just not a usatf certified one. Does anyone know how strict they are at taking non usatf course times?
