Optimization on the Prestashop product page 1.7

I need to correct some observations that https://pagespeed.web.dev gives me on the product page.

For reference you can review this product on pagespeed

Please indicate what observations you can correct and the budget for that.

I'll look forward for your answer.

Greetings.
