Can one MPPT device for a separate battery be excluded from DVCC?

Hi,

The battery i want to exclude from DVCC is a eksternal Start battery for the diesel generator. This battery cannot be a part of the main system due to the design of the Sinus converter inside the generator. Therefor the starterbattery must have its own circut. But since the generator can be in standby for long periodes, i use a PV and a MPPT to charge the battery and keep it in good condition. I therefor want to monitor the starterbattery and be able to send a warning if there is low voltage on the starter battery. I am able to monitor the battery with DVCC disabled, but wish there was a posibility to exclude this MPPT charger for generator from the DVCC calculation via software. Without adding more devices. Below you can se a snip of a part of the system to better understand the system.
