Restrict access to custom posts archive page

Hi. How is this custom posts archive page built? Is it standard WordPress or in a page builder? If you have a category or custom taxonomy that goes with the page you might be best off restricting the category or taxonomy.

Another option would be to add your restrict shortcodes to your child theme. See this article for more info: https://help.ithemes.com/hc/en-us/articles/360049324614-Restricting-Content-in-Template-Files
