What you are facing is the dual authorities which are prosecuting you for this matter. The DMV does not have to establish your alcohol level beyond a reasonable doubt. This means they are able to suspend a license with a far lower sowing of proof than the criminal courts. This is also allowed since you have a right to be out of custody but not to drive as that is a privilege. Good luck.
If you can wait the entire suspension period without getting a restricted license, then, yes, you can get your license reinstated at the end of the admin per se suspension by getting SR-22 insurance. In this circumstance, you will not need to attend DUI class.
The answer to your question is unfortunately yes. The DMV will require proof of completion of such a class to reissue your license. Our courts actually have no jurisdiction over your driving privileges, except in limited situations not applicable based on what you have shared.
Had a criminal case actually been filed against you, and the DA wished to dismiss the case, you ironically would have had a better chance of "setting aside" the suspension or appealing it. While I understand this does not apply to you, a case called Helmadollar allows a license owner who wins at trial to challenge a DMV suspension.
