Can Cylinder 2 misfire be a lifter if not d.o.d.?

I am asking because we have a 2008 Sierra 5.3 that we have done everything to in an attempt to fix it. It is not a D.O.D. CYLINDER, so can it possibly be that it needs a lifter swap if it is cylinder 2 and not a displacement on demand cylinder?

misfire can on any cylinder and can be from many sources. Let us know what you have already done.
spark plug
plug wire
Are you getting any noises ? Any other codes ?
All of the above twice. Everything has been checked off. Before we do the lifter, can that be the problem on a cylinder that is NOT d.o.d. is the question. Is that even possible.
sure, any lifter can go bad. Is it constant or intermittent ? I think they are usually accompanied with some noise from not pumping up correctly but not sure.
