Hey Andrew,
Welcome to the forums!
Michael is pretty much on the ball with his answer. It seems that the pins for i2c will be software defined and so most any pin (barring 5v, Ground, 3.3V, TX and RX) will be able to be defined as a send or receive i2c addressable pin!
The wonders of the ESP32-S3!
Cheers,
Blayden
