What should I do if I can't enter Thailand by the use date on my Non O immigrant visa?

Hello, I have a strange question. I just received my Non O immigrant visa and it says i need to use it by 3/24/24. I also just found out that there is a possibility that i would not be able to move to Thailand on that day, a few months after that due to a situation i might have to deal with. What would i need to do to extend the use by date? thank you for any help
