They're not taking appointments at this time. You will just have to show up. I went there to get the same thing. For a Real ID you must have your birth certificate, social security card, and 2 forms of proof of address. I got there at 6:30 this morning and was done by 9:05 thankfully. Hope this helps.
You can call or just show up. Bring a utility bill and two forms of id
