Exclude nodes referenced from another content type's node
In content type B (basic page), I named the refence field field_ref_article
1) Create view of content type A (article)
2) Add relationship &quot;Content Using [field_name]&quot;

3) Leave require unchecked

4) Add FILTER CRITERIA of [field_name]

5) Set relationship to [field_name] and operator is empty (null)

Overall should look like this
