I think most EVs keep cell voltage below 100% 4.2v, like 4.1v displayed as 100% and significantly increase lifespan. I’m not totally sure without looking it up though.
All cells are charged equally though, there are no unused cells that are at some other voltage. The battery management system specifically keeps all cells in series balanced, and the cells in parallel balance themselves. Locking battery capacity is done by restricting the voltage range across the whole pack, usually the top end, with some of the lower range reserved for limp mode.
