You decompose your own dump, take ME settings with FIT, exchange ME region in decomp folder with one from repository, build again. This ME region will have changed settings.
(That’s how it would work technically, but if this gives you the results you wish for of may brick your machine or… I don’t know!)
For flashing back you’d possibly need a programmer, unclear which regions the Lenovo recovery procedure will restore and if it’s able to work with a changed image, possibly not.
