I've made my own, the purpose of it is to prevent hot exhaust gases from entering the intake manifold, along with, if your EGR cooler decides to rupture you won't get coolant in the cylinders causing the head bolts to lift.
It's just another form of a EGR delete, if you do decide to go this way, I would suggest also a blocker plate at the up-pipe and EGR cooler connection or EGR delete up-pipe. Along with a tuner to turn off the CEL you may get for EGR insufficient flow.
This style of EGR delete allows you to block off the exhaust flow, without digging too far into the motor. The hardest part of the blocker plate at the up-pipe/EGR cooler connection, is getting to it. If you decide to use a EGR cooler delete up-pipe, you would need to remove the turbo.
Another EGR delete style is to pull out the EGR cooler and weld both ends shut, then reinstall. Looks factory.
With any EGR delete, you might need a tuner to turn off the CEL, depends on the year truck.
Ideally, a full delete works great. But if your worried about emission testing now or in the future, then go with Bullet Proof Diesel EGR cooler.
With any of these, it's important to keep an eye on your ECT/EOT delta, just incase your oil cooler starts getting blocked up.
