Inspect current dnf configuration.
$ cat /etc/dnf/dnf.conf

Assume yes for every question by default.
$ echo assumeyes=True | sudo tee -a /etc/dnf/dnf.conf

No questions asked.
Additional notes
Alternatively, you can change the default answer from no to yes, which is enough most of the time.
$ cat /etc/dnf/dnf.conf
[main] gpgcheck=1 installonly_limit=3 clean_requirements_on_remove=True best=True skip_if_unavailable=False defaultyes=True
Notice, the default answer is altered, simply press enter to confirm.
