There are a few different ways that you can hide additional information from WooCommerce product pages. One way is to use the built-in visibility options.
These can be found under the product data tab in the product settings. Another way is to use a plugin or custom code.
If you want to hide certain information from all products, then the built-in visibility options might be the best way to go. You can set it so that only certain user roles can see the information. For example, you could set it so that only administrators and editors can see the additional information.
If you want to hide certain information from just some products, then using a plugin or custom code might be a better option. For example, if you only want to hide information on certain products that are in a specific category, then you could use a plugin like WooCommerce Custom Fields. This would let you add a custom field to just the products that you want to hide information on.
In conclusion, there are a few different ways that you can hide additional information from WooCommerce product pages. The best method will depend on what type of information you want to hide and how many products you want to hide it on.
