I believe you can turn off the nvidia card with vgaswitcheroo:

% cat /sys/kernel/debug/vgaswitcheroo/switch
0:+:Pwr:0000:00:02.0
1: :Pwr:0000:01:00.0
% echo OFF | sudo tee -a /sys/kernel/debug/vgaswitcheroo/switch
OFF
% cat /sys/kernel/debug/vgaswitcheroo/switch
0:+:Pwr:0000:00:02.0
1: :Off:0000:01:00.0

At the moment I'm not even able to suspend or hibernate - hopefully
hardware support for these kind of hybrid gfx laptops improves in the
future!
