Fast port management after startup.

[mikl604]

Hello everybody!
In my project, IO17 is used as the power management output of the entire circuit. The principle is as follows: an external pulse to the mass starts DC/DC, the circuit gets powered. The ESP 32 is loaded and outputs the mass to IO17, which maintains the power supply after the end of the external pulse. What are the fastest ways to get mass at this output so that you don't have to wait for all ESP32 modules and functions to load? I place the command at the very beginning of the main program cycle, but there are many functions before it. Maybe there is a faster way?
