How can I add an agree to terms and conditions checkbox before users can add items to cart on specific pages?

This question may seem long, but on my website, I have add to cart buttons so people can purchase my products. I have 2 sections of products, digital downloads, and physical products. Both products digital and physical have the same add-to-cart buttons.

What I want to do is add the agree to terms checkbox below the add to cart button ONLY for digital products. Is there a way to add this checkbox on a specific page basis that connects with that specific page add to cart button?

I would be happy to show you my website if that helps! Thank you, guys!
