Yes, main thing is to let the turbo(s) cool down a bit, especially after high speed driving. If I pull off the highway to stop I usually let it idle for a minute or so before shutting down. Probably just cheap insurance.

We always did this with our tubo diesel tractors. The idea was that a hot shutdown would lead to oil being baked onto the bearings in the turbo impeller shaft (have heard it called 'coking") Over time, this would allegedly lead to quicker failure of the bearings in the turbo

This is definitely a thing if hauling a trailer or hauling ass. I learned this the hard way about 15 years, was hauling a cargo trailer from Texas to Florida for a tradeshow and was driving 80+ pretty much the whole way. Drove a full tank several hours non-stop, pulled into to get fuel and shut off the engine, gas fuel started it and tried to drive, it immediately went into limp mode. At the time I thought I had gotten bad diesel, but I watched several other people fill up and drive away with no problem. After 30 minutes I decided to call a tow truck to take me to the nearest dealer. An hour into the wait for the tow truck I decided to disconnect the battery cables and reconnect them and give it another shot, and it started up right away and drove fine. Pulled the codes when I got to Florida and settled, I don't remember the specific code, but it was an odd code, something about the turbo over speeding. After digging into it I essentially learned that if your ride the turbo hard you need to let it idle cool. I still have the truck, and after figuring that out have never had an issue again.
