As far as a quick fix/patch I suggest to just set it as a computed text field for the views you don't want a link.

ruby
    field :item,
          as: :belongs_to,
          only_on: [:forms]
    field :item,
          as: :text,
          hidden_on: [:forms] do |model, resource, view|
      model.item.label_maybe
    rescue StandardError
      false
    end
