The same as for any other Sendmail feature.  You'd have to edit
your local `sendmail.mc' or `hostname.mc' file in `/etc/mail',
add the new feature line, and run (while still in `/etc/mail'):

        # make
        # make install
        # make restart

The only FreeBSD-specific thing about enabling Sendmail features
is that in FreeBSD the default `foo.mc' file that is used is the
one that matches your hostname.  So if your hostname is currently
set to `foo.bar', look for `/etc/mail/foo.bar.mc' to add any new
Sendmail features.
