SEO modifications to bookmarks and product cards

Hello everyone,
As part of an SEO check of my website, I discovered significant disadvantages that occur when using the native product cards and bookmarks.

1: Bookmarks: Both the thumbnail image of the referenced publication and the cover image of the referenced post are loaded immediately and therefore have no image attribute loading=“lazy”.

2: Product cards: The title of the product cards is specified with a semantic HTML tag

This creates clutter in my document structure.

Are there any approaches or direct ways to fix these errors in the code?
Many thanks in advance

And: the product image doesn’t have an alt tag (bad for SEO); the product link doesn’t have a nofollow option (bad for seo if you use affiliate links)
