Configure EVDC Charging Mode?

[StephenE]

When using the MySigen app, you can configure your EVDC charger into "Fast Charging", "PV Surplus" or "Bi-directional V2X" modes. You can also configure the "Stop Discharging" point and the "Charging Power Allowed for EVDC".

I can't see any mention of these settings in the 2.8 Modbus protocol, which I assume is why there's no options to configure the EVDC Charger in Home Assistant (in fact, the only option is to turn the charger on/off in whatever current mode it is in). Has anyone had any luck finding out if these options are controllable or not?

(Disclaimer: I only got my stack installed yesterday so I apologise if there's a known work around)
