Hello

You can configure the pins for extra flags using GPIO.H functions

like: 

gpio_pin_configure_dt(&led, GPIO_OUTPUT_ACTIVE);

where the label led is obtained from the overlay using

GPIO_DT_SPEC_GET(DT_ALIAS(led0), gpios);

Thanks for reply !!

I do want to change the application code,

using overlay file want to modify the pin status.

In which location/section of overlay file I have to use below line

gpio_pin_configure_dt(&led, GPIO_OUTPUT_ACTIVE);

This line should be used in main code, not in the overlay.
