You can try online to renew license. If you are eligible, it can be renewed online. https://www.dmv.ca.gov/portal/driver-licenses-identification-cards/driver-license-id-card-online-renewal/
As far as I know DMV in general is not offering new appointments at this time. I would suggest you to make the time and go in person to try to get either an appointment or maybe if you are lucky and there is not too many costumers, maybe get your license process done the same day. Good luck!
