If you do not want a specific page to appear on your published website, that is not a problem. In the Page Properties panel, you can select the option to exclude the page from being published.
Here's how:
In the Website Builder, click the Manage Pages button, which is located in the main toolbar, next to the Site Builder
menu.
The Page Manager opens and the pages associated with your selected design template appear:
Select the page that you do not want to appear in your published website.
In the Page Properties panel, click the Do not publish page check box.
When you publish your website, the page will not be published.
