Adding esp32-s3 can be easily done in the firmware. You need to start with defining the peripheral pin configuration #define. As far as I have studied the firmware, there is no difference between esp32 and esp32-s3.
The firmware code is not very readable, but the definitions are clearly written. You can copy the robot profile from the image and reassign the pins. True, the esp32 has some subtleties, not all pins can work as output. But since you have a working robot, the correct configuration has already been taken care of.
