Where to toggle automatic updates checking? (dom0 and all qubes)

From qubes-gui-configuration:

  1. Check for dom0 updates
  2. Disable (Enable) checking for updates for all qubes.

How to make changes via terminal (or bash)? What configuration files need to be fixed?

I think it is disabled by qvm-features <vm> service.qubes-update-check ''


probably the easiest way for most is via the Qubes Global Settings application.
