# systemctl mask NetworkManager.service 
# systemctl poweroff

Booted after G3 - mechanical off:

$ systemctl is-enabled NetworkManager.service 
masked
$ systemctl is-active NetworkManager.service 
inactive

# ethtool enp3s0 | grep Wake-on
        Supports Wake-on: pumbg
        Wake-on: g


As shown, original device state - WOL (magic) is enabled.


$ grep wake /etc/NetworkManager/NetworkManager.conf | grep -v ^#
[connection-wake-on-lan-default]
ethernet.wake-on-lan=0

# systemctl unmask NetworkManager.service
# systemctl start NetworkManager.service

$ nmcli --fields 802-3-ethernet.wake-on-lan connection show enp3s0 
802-3-ethernet.wake-on-lan:             default

# ethtool enp3s0 | grep Wake-on
        Supports Wake-on: pumbg
        Wake-on: d


As shown, "ethernet.wake-on-lan=0" has no effect on disabling NetworkManager's WOL management.
I wonder if such a possibility exists, at all.

BTW the NetworkManager's WOL implementation - to disable WOL on devices per default,
is somehow contradictory.
