You can toggle the visibility of a sheet from the main admin side list of all sheets. Just hide the ones you don’t want anyone to see yet.
Please see the documentation here:

I was looking more for pages 1 – 20 one page and pages 21 – 23 on another page. Was hoping for a quick way rather than needing to list 1-20 individually. If I need to, I will, but looking if there was another way
You could use the Groups extension and then assign the first 20 to one group and then rest to another group, and then use the shortcode for the group to show, so you can show one group on one page and another group on another page.
