Most online OEM parts stores still don't have '23 applications available, delay is normal for new models every year.
There is a section in the owners manual "Items to initialize" if the 12 volt battery is disconnected. That is all you need do.FYI if you disconnect the negative battery terminal on a car with Toyota Safety Sense (TSS) it will give some warnings on the dash about the pre collision system failing. I just had to drive maybe one mile and restart the car and the message went away.
