No. You do not ever want to block or restrict air flow to a cold air return.
FOR TWO REASONS: ONE- No circulation means no HEAT (or Air Conditioning) so why have the unit in the first place? It cuts back on the efficiency of the unit to do its job, and you end up just wasting money to run a fan that does nothing. {To fully understand, try blowing into a bottle with your mouth directly ON the lip..., nothing out means nothing IN!}TWO- It causes the the coils on an Air Conditioner to FREEZE over and further restrict the air flow and then you have to turn off the AC and wait for it to thaw. That also applies to closing your vents in each room/zone, one place I used to work found this out the hard way! Then you are back to the first reason again!
