How to remove no-cache header?

My hosting service Dream Host has brought to my attention that my site is experiencing a significant slowdown in performance from the awesome support plugins use of a no-cache header. This is preventing my server’s cache from working properly.

Once the plugins is disabled, the ‘no-cache’ headers no longer
appear and I get a HIT (x-varnish: HIT header) when running a cURL on the site.

But I would like to continue using awesome support. How can I get the plugin to stop setting “no-cache” headers
