Help needed: Custom CSS code

We installed the following from ThemeForest: CRUX - A modern and lightweight WooCommerce theme via Wordpress.
We need help with:

  1. the previous and next navigation option under the product list. For some products, we would not like the option on the page at all as they are single, stand alone products. For example this one: and this one: For other products we would like the option as there are many different options under a single banner, for example all the ADD-ON product options we offer.
  2. not having the SKU, Category and Tags appear on the product pages (towards bottom of page) for all product pages.
    Could someone assist with the custom css code to make this happen please?

Best option is to ask the author -

Point 2 is easy but making point 1 “optional” may require more than CSS
