Could possibly downgrade to a slightly older calibration maybe, but I just leave it personally. I look at it now as a safety feature more than change and nuisance.

Someone else may know how to undo it tho that would chime in.

It has nothing to do with the engine or its ECM software at all. it is in the cab module that does this..,. the paccar software is needed.. and even then, it may not be an option, as it is a safety requirement on newer model trucks.
