Hello,
I see.
If you don’t need e-commerce part then just don’t install WooCommerce and other plugins for WooCommerce like Wishlist, Compare etc.
Edit header using header builder and remove e-commerce elements like cart, wishlist https://www.youtube.com/playlist?list=PLMqMSqDgPNmDu3kYqh-SAsfUqutW3ohlG
Build pages without e-commerce elements like Products, Product categories using blog elements, texts, headings etc.
