Best approach to turn off brightness before begin() ?

[martinroger]

I am aware of the ESP_PANEL_BOARD_BACKLIGHT_IDLE_OFF macro when using custom boards, however the value for this is obviously "fixed" if using a supported board.

My target is to be able to change this parameter to OFF or ON programatically before the begin() call for the Board . Is that possible ? If so how ? (Without using a custom board configuration file)
