Driver's License from out of state, GC Interview next week

Hey guys. We got our I-130/I-485 interview coming up at the Nashville FO. I currently have a state driver's license from a previous state I've lived in (years ago). Spouse has license from our current address. I was hoping for the EAD to be approved so I could get a driver's license since I am currently unable to get a license in Tennessee (Overstay since child and no SSN). I currently have the TN Driver's Services page printed out which shows I cannot get a license and am prepared to explain this. Is there anything anyone can recommend that I should do to prepare or be ready for? Any tips?
