No.

Many do have a vaccum or electrically operated throttling valve(s) for the

purposes of increasing swirl at low speed, brake servo vacuum and/or 
improving EGR performance.

They never shut 100%, and given a diesels ability to suck hard it would
get 
enough air to run on tickover even if it smoked like a bugger.
