How to I turn off esp32 lora power led to save battery?

how to turn off esp32 lora power led?
I ask about this because I need the maximum autonomy while using the minimum battery in deep sleep mode. Therefore, I need to turn off all LEDs, including the power on and any activity LEDs.
Since I already thank you.

When using battery power, the power indicator will not light up.

What a good information!!
I saw it here now.
Thank you very much
