Ruby GraphQL lazy loading dynamic scope

I am currently struggling with a relation/scope that is dynamic - based on the current time for example.

How do I lazy load/batch the query efficiently? I am already using Dataloaders but they don't seem to work with (dynamic) scope and they are still triggering N+1 for this case.

module Types
  class PersonType < BaseObject
    field :future_events, [EventType], null: false

    def future_events
      dataloader.with(Sources::ActiveRecordObject, ::Event.where("start > ?", Time.zone.now), column: :person_id).load(object.id)
      # Event.where("start > ?", Time.zone.now).where(person_id: object.id)
    end
  end
end

module Sources
  class ActiveRecordAssociation < GraphQL::Dataloader::Source
    def initialize(model_class, column: :id)
      @model_class = model_class
      @column = column
    end

    attr_reader :model_class, :column

    def fetch(ids, scope = :all)
      records = model_class.send(scope).where({ column.to_sym => ids }).index_by { |record| record[column] }
      ids.map { |id| records[id] }
    end
  end
end
