You would have to edit the
cta_featuredthreads_featured template and add the link directly.
Edit the
cta_featuredthreads_navigation_tab_links template and remove this code:
Code:
<xen:if is="{$xenOptions.ctaFtFeaturedThreadsArchive.enabled}">
<li><a href="{xen:link 'threads/featured-archive'}">{xen:phrase cta_ft_featured_threads_archive}</a></li>
</xen:if>
