What you need "disable" to mean?

Switching the pin to an input with gpio_set_direction(gpio, GPIO_MODE_INPUT) or gpio_config() will disable the output driver and put the pin into a Hi-Z state. This is probably the closest you can do to "disabling" the pin.

Hi,
I think pir sensor has a Potentiometers (knob) to change the sensitivity and also the duration until the output should be high if a motion is detected. changing the duration knob for e.g to min ( 3 seconds) and then including a delay of 3 seconds in the code would be one of the feasible solutions.
Thank you
