RE: How can I hide Entities Knowledge/ Analytics and Insights
Hi partner,
Do you mean these two groups of Customer Service sitemap?

If so, we need to edit the sitemap of Customer Service.
Go to Advanced Settings > My Apps > open the app designer of Customer Service Hub.

Edit the Site Map.

Click Analytics and Insights, then click Delete. Click Knowledge, then click Delete.


Save and publish.
In this way, Knowledge and Analytics and Insights in the sitemap will be hide.

In addition, I would recommend you add the Customer Service Hub's sitemap into a custom solution and export it as a backup before hiding them, so that you can import this solution to restore the sitemap later if necessary.
