hiding breadcrumb navigation from one product page only

I have a product page that's not linked to my store. I'm using it to put products that I don't want to appear in my other product pages. How do I remove the breadcrumb navigation that appears when customers are looking at individual products on that product page? For example, the page for gift cards. At the top, it is showing "Gift Cards and Custom Services > Gift Cards" with the first part linking to the product page. Basically I don't want customers to be able to access that particular product page and see the items I have in there. Thanks.

Can you share link to product page? We can check easier
