Not really. Nexus 6p 6.0.1 here and first I got the darn notification that I don't want. So I started by trying to disable the three suggestions. This didn't work in autostarts as it's not 6.0 compatible. Rom toolbox lite said it managed to disable them, and indeed after reboot the notification is gone but guess what I end up with instead: the damn wakelock!
The wakelock in 6.x isn't draining,although it shows up in BBS.
