Creating a view that excludes entity referenced nodes
Views Reference Filter might help you:


  This module provides the feature missing in Views module - subquery filter for IN (NOT IN) condition, such as (quite informal):
  
  SELECT n.title FROM node n WHERE n.nid [IN | NOT IN] (SELECT n2.nid FROM node n2 WHERE ...)
  
  or
  
  SELECT n.title FROM node n WHERE n.node_reference_field [IN | NOT IN] (SELECT n2.nid FROM node n2 WHERE ...)
