Do I need the unbound anchor service?

systemd-analyze blame is showing the following:

I am just wondering what the unbound anchor service is used for? I have three machines running fedora 31 and only 1 is showing this as slow service.

systemctl status unbound-anchor

● unbound-anchor.service - update of the root trust anchor for DNSSEC validation in unbound
   Loaded: loaded (/usr/lib/systemd/system/unbound-anchor.service; static; vendor preset: disabled)
   Active: inactive (dead)
     Docs: man:unbound-anchor(8)
man 8 unbound-anchor

Good Luck!
