Is there any way to use Ember 1.10 / 1.11 with handlebars instead of HtmlBars?

I want to upgrade libraries using at project. But I have no ability do it in one step. So i'm interesting in updating step by step.

I know that since 1.10 ember support HtmlBars. But cat I tweak something to use handlebars as temporary template engine?

I use ember-cli
