How early can I renew my license?

Okay so I have to renew in October but I’m not going to be home in October at all so how do I renew? Can I renew early in July or August?

It’s very important for me to get renewed because I’m turning 21 (so that “UNDER 21” text will go away) and now I’m a registered organ donor so I want to make sure that the “organ donor” thing gets on there ok so people can know my wishes if something bad happens to me (heaven forbid).

I’m kind of new to this…never had to renew before :) Thanks.
