Does anyone know if obtaining a driving license is different for a Thai citizen than us expats?

I will do my first 90-day report in Bangkok (since moving here in September) at the end of this month. Then I will ask for a residence certificate. Then I will renew my driver's licenses. How long does it usually take to receive the residence certificate? Is there an express/next day service like in Chiang Mai? How long is the wait in the DLT app? Should I make an appointment now or wait until I get the residence certificate? Anything I can do to reduce the time I'm driving on expired licenses would be great. Thanks!

Back home in Thailand finally but I can't find my thai driving licence, can I just get a new one from the driving centre or will I need to do my test again 😫

Thanks
