I do not think so.

My conf file has this sample snippet:

  # Uncomment to enable DNSSEC validation.
  #
  #auto-trust-anchor-file: "/var/unbound/db/root.key"

I've not uncommented the above.  Additionally, I've not run the
command to generate /var/unbound/db/root.key (it does not exist on my
system).

I have a pretty basic setup.  It's not exposed to internet traffic.
