You cannot. You must make an appointment, and they are about 10 - 15 days out as of 8/1/20. I had 1 idea but I don't think this will apply to you, but just in case; A car dealership is able to switch REGISTRATIONS, or give you new plates and registration w/o going to DMV. If you know anyone that works at a dealership or if you feel like calling any dealership, maybe they can answer your question or help you solve your problem.
Make appointment downtown and when you get there say you have an appointment for instance you get there at 915 say you have 930 appointment and they let you in then when you get to the counter tell them your a walkin
