If you go to YouTube you can find videos about repairing your turbo. One recommendation was to drive it often and and occasionally hard. They had one good recommendation when in storage for extended time to plug the exhaust so moisture can't get to the turbo and cause rust and sticky operation.

Yes, letting it stand for many months without driving it could result in rusting things up and the ring on the VGT will not slide properly in the hot side portion of the turbo. This would prevent the turbo from working properly. Having the exhaust brake working also prevent the VGT system to stick as the EB is using the VGT on this turbo for exhaust braking action.
The problem with my turbo is not the hot side ring, the ring goes in and out no problem and the mechanism is not worn. The problem is in the VGT mechanism itself which is attached to the turbo. This mechanism could freeze up the gears or motor if moisture or coolant gets in. It could also fool the position sensor. You could probably prevent seezing if you drive it at least once every couple of weeks, but coolant or moisture should not get in there at all in the first place, it is all sealed up to prevent it.
I could not find any videos for the HE341VE turbo, there are some for the HE351ve turbo introduced in 2005 which is close to mine, except that the VGT mechanism is using a brushless electric motor. The HE551VE is another version that I think was used starting somewhere in 2005 and up probably but I am not sure.
My turbo is at page 7, figure 2. If you want to know which type you have, just look under you engine. If you see a black motor sticking out, it is a HE341VE.
