How to block Pinterest from product images?

Is there a way I can block my product images from being pinned in my Woo Commerce cart plugin? What code and where would I put it to do this?

I have been able to use WP Content Copy and No Right Click premium to add watermarks and prevent saving images with right clicking. I also have installed Pinterest Blocking and it does a good job of blocking the blog images, but my product images in your plugin is still allowing them to be pinned. This is what content thieves like is to steal my product images and use as click bait. You can’t right click them but the work around is you can still pin them and when that happens it strips the watermark off. What code could I use and where would I put it into your plugin prevent them from being pinned. Thank you for any help you can provide.
