Even though technically dnf system-upgrade can --download-dir to a

Somewhat off-topic, but you can symlink /var/lib/dnf/system-upgrade to
somewhere else and all the downloaded packages will be stored there and
the upgrade will still work. (As long as the linked storage is
automatically mounted at boot.) I've even used a USB flash drive for this.
