Can I set the internet termination date as the end of the termination?

Computer

This month, the three-year Internet contract is over, and as soon as the contract is over, I want to move by receiving free gifts on another Internet.In that case, I'd like to set the date of termination exactly on the date of the end of the contract, but is it possible to make a reservation for termination in advance?
