Here 4 LED control

Hi, I am using here 4 GPS with cube Orange plus. The issue I am facing is that I am unable to turn off leds lights of the GPS. I change the parameter ntf_led_bright = 0 and led turns off

But every time i reboot the system the GPS light turns on again in a cyclic led pattern (green-violet-red)
I have to rewrite the parameter every time I boot the system.
Please guide me regarding this
