I have a little experience with these engines. should you disable it? Absolutely 100%!
For a minimal improvement in fuel economy they took one of the best V6 engines on the market and turned it into a pile of trash that is burdened with all sorts of issues, all of them expensive to repair.
Oil burning, cylinder and cylinder head/camshaft damage, sludge, worn active engine mounts that cost a small fortune, expensive spool valves that fail, an OLM that doesn't even come close as the oil is long finished before it trips and all this for a couple of MPG.
It doesn't take an engineer to figure out that if the active engine mounts are needed just to keep the engine from feeling like its going to hop out and run down the road on its own that something isn't running quite as smoothly as it should.
