You can. With 23 years having passed since your last DUI, it probably won't even hamper you in finding employment as a CDL driver once you've graduated.

You can, but nobody will hire you.
True
Sure, you can get a CDL. Whether you'll be able to find employment in the industry is another matter, however.
October of 1986.
A past DUI conviction won't prevent you from being able to get your CDL, but, depending on how recent it was, it could prevent you from finding employment as a CDL driver. If your DUI conviction was within the past five years, you're better off finding a different line of work to get into.

Not as long as the resulting suspension period from your DUI conviction is in effect. If it has passed, and you've reinstated your licence, you can upgrade it to a CDL. If your DUI occurred within the past 10 years, your prospects of finding employment as a CDL driver are slim. If it's been within the past five years, you'd be best advised to pursue another career path, and not waste your money getting a CDL.
You can get the license, but don't hold your breath waiting to get hired - especially if either of those DUIs were within the last seven years.
