Can I be allowed to resign from the army if I have been charged with domestic abuse for 25 years?

I obtained a deferred adjudication for domestic abuse charges in 1996, but I did not finish the probation successfully. Somehow, this has never been found in my 25 years in the National Guard, and 18.5 of those years, I have been on active duty with the Guard. I’m set to retire in January 2022. I’ve got to renew my security clearance, because this is now a concern on the SF86, because I don’t want to lie on the official form.
