The page had a row for the case where dnf-automatic is absent and nothing for the case where it is present, so installing it made the setting disappear rather than appear. The switch enables downloading only, which is the shipped default and the right one to keep: a machine that installs packages unattended can reboot into a kernel nobody chose. Downloading ahead of time is what makes the install quick when someone does choose it, and the row says exactly that rather than implying updates apply themselves.
