Yes — Rules → Cache on. By default it is Everywhere on the site, which is what a cache is for. If you want less than that, choose Only what I choose below and tick the kinds of content, the archives and the individual pages you want.
With Everywhere on the site, a new custom post type is cached automatically. With Only what I choose below, only the post types you have ticked are cached, so tick a new one when a plugin adds it.
