disable updates from command line in Ubuntu 16.04

Is there any gsettings schema to select "Never" on

system settings->software and updates->updates->automatically check for updates

Any other command line option to disable automatic updates is right for me.

Thank You

Thanks to suggestions from Norbert and doug I came up with this solution:

sudo sed -i 's/APT::Periodic::Update-Package-Lists "1"/APT::Periodic::Update-Package-Lists "0"/' /etc/apt/apt.conf.d/20-auto-upgrades
