Using COEX0 to switch 3V3 supply to external GPS

[dennisnguy]

How can I use COEX0 pin as a GPIO to enable the 3.3V for using an external GPS?
I would like to set COEX0 pin to high as an GPIO.
Thanks in advance

Hi,

Do you want to use an external complete GPS module or controlling external LNA/GPS active antenna ? 
Have you looked at this guideline (How to use the nRF9160 Feather - Blogs - Nordic Blog - Nordic DevZone) for using GPS module on nRF9160 ? It covers how to enable and use COEX0 pin for controlling GPS module.
