i'm not exactly sure why you'd want to downgrade the battery health capacity of the battery, but okay.
you can do it with the JC V1SE programmer. i can't speak for the 11, but i've changed the S/N for 7(+), 8(+) and SE2020 batteries so the factory ID and the read ID will be the same in 3uTools. i've changed the health reading in throwaway batteries just so i can know how to do it, but i would never do so to misrepresent the actual capacity of a battery that i was selling (kind of like rolling back the odometer of a car)..
