I known that the CAR_SEAT_FRONT_XX is the first row, and the CAR_SEAT_REAR_XX is the second row. Right?

I can't imagine which seat the CAR_SEAT_REAR_LEFT_BACK and CAR_SEAT_REAR_RIGHT_BACK refers to.

I'd assume it's the third row in the mx, but there's a CAR_SEAT_THIRD_ROW_x. Maybe it's ventilated seats?

It looks like the CAR_SEAT_REAR_LEFT_BACK and CAR_SEAT_REAR_RIGHT_BACK were created when legacy message types were translated into protobufs. In the legacy protocol, they referred to seat heaters for some pre-2021 Model S vehicles. However, those Model S vehicles don't support the new protocol, and so the protobuf entries are vestigial.
