How to set ACF field group only for specific posts?

Question

WordPress

I managed to set the fields for a specific post type and exclude from the post where I do not need these fields. But I need the opposite. Set these fields only for 2 specific posts. But if I do this, their fields disappear in the post itself, but they are on the site. Why is that?
