You can use the unbound Handlebars helper helper to do this at the individual property level.
Work is underway on the #unbound auxiliary block, which would be good for what you are trying to do: https://github.com/emberjs/ember.js/pull/321
Another approach is to provide a simple Handlebars template in your views. None of the output will be linked.
App.UnboundView = Ember.View.extend({ template: Handlebars.compile("output is: {{msg}} here"), msg: "not bound" });
Here is a jsFiddle example: http://jsfiddle.net/ebryn/zQA4H/
