title: Disable custom post type single page only for specific posts
body: <p>I know when registering the CPT there are options like <code>public</code>, <code>publicly_queryable</code> and <code>query_var</code> but this will apply to <strong>ALL</strong> of the posts. I want some posts to have the single page and other posts to not have it.</p>
  <p>Eventually I'll use ACF to determine which ones but for now I'm okay manually indicating by id, slug, or anything else.</p>
