we don't think that it's possible. You should ask this question on plugin's forum if you want to be sure about it. But if you want to have catalog mode, you must activate this feature under Theme options > Blog, Portfolio & Shop > Shop section.
If you have this option activated and "Add to cart" button won't disappear, please deactivate all extra plugins and make sure you don't use any cache because this option works for sure.
