Is a views page an entity?
Can I reference a views page via an entity reference field?


Not out of the box, but you can use the Views reference field module to get that functionality:


  In Drupal 8, Views are now identified as entities and the core Entity Reference Module is able to reference Views, however not Views displays. This module leverages core entity reference module functionality to add the display ID so that a View can be rendered in a field formatter.
