Prevent Add to Cart or Checkout Page - Certain Items

I have a section on my online store for in-store items only. I have created custom template for this collection and products within. I have done this so I can use them in the merchant feed for Google. They are starting to show on Google however there is a buy now button on the products in the Google local free listing results that when clicked brings them to the cart with the item.

I have deselected physical item, and made The product page template with no add to cart buttons or anything.

In my Google merchant Center I have my checkout link verified and working for my online items. But it seems to be working for the in-store only items as well…

Is there a way to prevent these items from showing up and check out when someone clicks on them from Google free listing results?

As per our understanding Google feed have product URL and as per you statement you have removed the checkout/ add to cart CTA from the product page. Would you mind sharing the URL you are getting from the feed for IN-Store products.
