Activate cpu when booting the NX

I am currently using a jetson NX card.
I would like to activate my 6 cpu when booting the NX.
I tried to do this through a service like the following:

Here is my bash file. When I run it manually I manage to launch the 6 cpu.
#! /usr/bin/bash
echo 1 > /sys/devices/system/cpu/cpu0/online
echo 1 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu2/online
echo 1 > /sys/devices/system/cpu/cpu3/online
echo 1 > /sys/devices/system/cpu/cpu4/online
echo 1 > /sys/devices/system/cpu/cpu5/online

Here is my service :
Description=cpu service



My bash file does not start via the service … I don’t understand why … could someone please help me?
Thank you

There’s a power mode to enable 6 CPU cores:

Please execute sudo nvpmodel -m 2
