If you get your drivers’ license before you’re 21, does it always expire on your 21st birthday regardless of whether you got it at 16 or 20?

So I know that drivers’ licenses are issued differently to drivers under the age of 21 in America compared to drivers who are 21+. But I was wondering if they expire on your 21st birthday if you get your drivers’ license before you turn 21 regardless of when you got it.
