Haven't done it, but I think you can just unbolt the egr fitting from the back of the intake manifold, and bolt down a block off cover. Then just make sure all of your vacuum fittings are plugged. I'm sure someone that has done it will chime in.

I desmogged my 88 GW when I swapped in an edlebrock carb and non-EGR intake. Basicly I have removed everything and plugged the exhaust manifold holes with bolts.(where the air injection was) I run vac for power brakes and the vac ball to the manifold, and vac for the vac advance and PCV to the carb. My vapor canisterhas a broken valve, and I have not figured what to do with it yet.

If you remove the EGR you effectively lean the air/fuel mixture. This can lead to spark knock (AKA ping), depending on the engine. Pinging is not good for the engine, so it's a good idea to richen the mixture. On the 2150 carburetor this is done by changing the jets. Mine went from a size 55 jet to a 60 when I took of the EGR. Good luck,
