Is there anyway of turning the pv assistant max charge voltage down?

You set the grid charger voltages internally in the inverter lower. Since that is the settings used for AC PV charging.
Or in DVCC you can cap battery voltage. But that is global if you have DC mppts it affects that too.
I am having to voltages on all devices, as they are 12s 3.7 s dvcc was working but now just shuts off charge
Well. Daly is not on officially supported so won't be as refined as others.
The PV assistant is not really as refined as the on grid ESS. Usually DC PV finishes the charge off the AC PV parks off close to finish. Maybe consider that as an option.
Or you could set the ramp down Hz a bit differently to try change min production amount. To prevent the overshoot which is likely the problem here. I do see that Daly lacks fast enough balancing. Not sure if you have done extra on your pack for that?
Total guessing here as I also don't know what AC PV you have either. Just notes from what I have seen in the field.
all sorted i had to play with some settings in dbs config to be able to use dvcc as 3.7v cells etc etc
it was shutting doen and not allowing charge. now freq shift working fine
