ESP32 SIM800L configuration

Can this all in one board be configured with ESPHome SIM800L component?

If so, what is the pin configuration for the UART?

uart:
  baud_rate: 9600
  tx_pin: TX
  rx_pin: RX

I understand it can work

The schematics are here GitHub - Xinyuan-LilyGO/LilyGo-T-Call-SIM800
