Could you hide the “availability” and price fields too?

I’m trying out this plugin, and it’s working alright. However, I have two problems:
1. I don’t want the price to be shown. I can leave that field blank, but the currency switcher plugin will still insert the currency in the empty price field
2. The availability is being displayed. I have physical products, and I want their stock status to be visible

Would it be possible to get this plugin to completely disable both the price and availability/stock fields for non-purchasable products?
