Hi! is it possible?

No. There is only one Green Power LED, which is NOT connected to GPIO.

Hi,

You can change turn on/off the led with this command :
echo 1 > /sys/class/leds/radxa-zero:green/brightness
echo 0 > /sys/class/leds/radxa-zero:green/brightness

and probably make flashing by changing this :
/sys/class/leds/radxa-zero:green/trigger
