ESP32 T-Call SIM 800 disable pwr button

[yzerman]

Hello, I would like to ask you if it's possible to disable PWR button (which is located on one of the sides) via the code? Is it connected to GPIO?

Based on some googling this looks like this board is a "LilyGo SIM800L IP5306" ? Its schematic shows the button is not connected to any GPIO, it connects (via R57) to the KEY pin of its IP5306 PMIC (controlling power on/off). It also connects (via R53) to the enable/reset input of the ESP32.
