Is there a possibility to skip the tuple-diff check at update-changesets?

Hey,
I want to use the update changeset, but want to skip the tuple-diff-check, which results in a extra sql, of the tuple, which is too expensive?
Is that possible? Or do you recommend not using changesets in that case?

What do you think about following workaround (using command and changeset)?

update(id, items.changeset(Changesets::UpdateObjectChangeset, item).to_h)

Here’s my custom changeset:

module Test
  module Repositories
    module Changesets
      class UpdateObjectChangeset < ROM::Changeset::Update
        include Deps["current_time"]

        map do |tuple|
          tuple.except(:id, :created_at).merge(updated_at: current_time)
        end
      end
    end
  end

Another related question:
How to apply the changeset to an array of tuples? Following…

items.changeset(Changesets::UpdateObjectChangeset, items) # items is an array

fails with …

NoMethodError:
       undefined method `except' for [] at the custom changeset

Thanks
