Holder: How to hide comments on pages but allow on posts?

Using Holder template, how do I allow comments on posts but disallow them on pages? I was doing this prior to installing Holder by selecting Page Attributes --> Template --> Front Page Template. I no longer have this option now that Holder is installed.

Basically, I don't want people to be able to leave comments on my About Us page or on any of the static pages, but I do want comments allowed on the posts.

Thank you,
