Welcome!
After creating a post type using pods, You can navigate to Advanced options and uncheck Public and Publicly Queryable.
Note: There are parameters like exclude_from_search, publicly_queryable, show_ui, and show_in_nav_menus that are inheriting value from public. You need to set them manually if you want to use them.
