Here follow the commands given:

root@zanac:~$ cat /sys/bus/pci/devices/0000:04:00.0/power/wakeup
enabled
root@zanac:~$ echo disabled > /sys/bus/pci/devices/0000:04:00.0/power/wakeup
root@zanac:~$ cat /sys/bus/pci/devices/0000:04:00.0/power/wakeup
disabled
root@zanac:~$ poweroff

But after a couple of seconds the system still turns on.
