Power optimisation - Cutting power to 4g modem HAT

[armsto88]

Hi there,
Perhaps not directly related to Birdnet Pi, although an important part of my current project, any assistance appreciated.

I have a Waveshare 7600 G-H M2 HAT attached to a Raspi 4B
https://www.waveshare.com/wiki/SIM7600G-H-M2_4G_HAT#What.27s_On_Board

Im trying to optimise power consumption and cutting the power to the modem during a specific time frame would be ideal. I notice on the pinout definition (Link above) there is an option to switch the 4g module off/on via gpio pin. Due to my inexperience and failure to find any material online in which is clear to me, i need help in realising how to do it.

I assume this only cuts power to the 4g module only, if there was a way to disable power to the entire HAT via a pin, that would be better. So far everything i have read suggest that is not possible.

Thanks again for your time.

Cheers
Tom
