How add query to EntityListBuilder
Although not exactly a duplicate of How to make EntityListBuilder sortable? it is essentially the same answer as Berdir wrote,


  You'd have to implement the query logic yourself.


For instance, BlockListBuilder overrides getEntityIds to add a condition on the theme key.

However as Berdir also notes,


  For content entities, I would strongly recommend to rely on the views
  integration instead. List builders are limited in functionality and
  mostly useful for config entities only.
