How i can read Solarcharger MPPT Load power with modbus TCP?

I have a system with of an MPPT charge controller with all 12v services are connected to the load output. I would be interested in reading this value with the Modbus TCP protocol, but unfortunately I cannot find the value in the Modbus register... You do you know something?

I down't have a MPPT with a load output.
But in the Modbus-TCP register list from Victron is no load under .solarcharger.

Can you look in your GX, if there is a other .dcload device showing up?
It is under settings, services, modbus TCP, avalible services.

If yes, you could calculate it from U*I with register 4300 * 4301
