Smart batteryprotect 220A over-voltage disconnect

So I have read that the over-voltage disconnect is 32.6V for 24V systems. I find that to be a bit high. Can this value be lowered? Is there some other piece of equipment that can protect me from such voltage surges? Had an episode earlier where the diesel engine alternator went on a rampage and the lithium battery BMS did not disconnect in time. A lot ruined electronics down the line…
