Board definitions specifically for this board
What’s a “Lilygo t-display s£”?
It’s a lilygo esp32 s3 board with a builtin 1.9" TFT display
GitHub - Xinyuan-LilyGO/T-Display-S3 says to just use the generic “ESP32S3 Dev Module” definition. Arduino-ESP32 does not have a board definition specifically for this.
So, you should be able to just use esp32-s3-devkitc-1
