dpkg

I have a shell script to automatically configure new Ubuntu virtual machines for my purposes. I would like this script to install and enable unattended-upgrades, but I cannot figure out how to do so without user interaction.

The usual way to enable upgrades is dpkg-reconfigure unattended-upgrades, but of course that is interactive. The noninteractive front end avoids asking any questions at all, and the text front end seems bound and determined to do its I/O with the tty and not with stdin/stdout.
