Determining the current configuration

The current configuration can be queried by running:

apt-config dump APT::Periodic::Unattended-Upgrade

Which will produce output like:

APT::Periodic::Unattended-Upgrade "1";

In this example, Unattended Upgrade will run every 1 day. If the number is "0" then unattended upgrades are disabled.

The files in /etc/apt/apt.conf.d/ are evaluated in lexicographical order with each file capable of overriding values set in earlier files. This makes it insufficient to view the setting in /etc/apt/apt.conf.d/20auto-upgrades and why it is recommended to use apt-config.
