Edit Specific Product Layout on Woocommerce Shop Page

Im working on the Enfold theme for my client and want to write a conditional statement for a specific product on the woocommerce shop page.

We have a dummy product, but we don’t want the product to link to the product page. We want it to links elsewhere.

I need to write a conditional statement that will change the link on the product image:

If product ID {
Custom link
} else {
the_permalink

However, I’ve checked the Enfold theme folder and the Woocimmerce folder is not present. I see you have integrated woocommerce using a configure – which I’m not familiar with.

What file/files do I need to edit to make the above possible?

Thanks
