Turning off the pwr-led on GrovePi Board

Hi, is it somehow possible to turn off the pwr-LED on the GrovePi Board?

I could disable all the LEDs on the raspberry pi with the following commands:

sudo sh -c 'echo none > /sys/class/leds/led0/trigger’
sudo sh -c 'echo none > /sys/class/leds/led1/trigger’
sudo sh -c 'echo 0 > /sys/class/leds/led0/brightness’
sudo sh -c ‘echo 0 > /sys/class/leds/led1/brightness’

Does something similar exist for the LEDs (pwr, rst) on the GrovePi Board?

Thanks for your help!
