how to turn off included notification when running ansible2 playbook

Hi all,
Whenever I run ansible 2.0 playbook it states al the included files in the list of running tasks. is there a way to make it less verbose and turn off this kind of statements?

In Ansible 2.3.0 there is a dense callback. Do not know what is included in a condensed output

* Added a new "dense" callback to produce a more condensed output
