Change layout product page

Hello,

I want to change or customize the layout of the product page. My question is whether this can be customized with a code showing just 2 rows with 4 products each. And in full width of the screen. I do not use a sidebar, so there is enough room to spread the products over the whole page.

This website shows the way we want it to spread the whole page full width: https://letoile.store/lighting.html

And this is our page now: https://www.cocoonconceptstore.com/winkel/

Thank you in advance.
