How do I access Aux input on master Quattro inverter using modbus?

Starting to regret my decision to go with a colour GX over a Cerbo but I am hoping I can still access the signal via the aux input on the master inverter.

I am just after some guideance on how to do this with modbus as there doesnt seem to be a register for it in the spreadsheet.

Incase there is a better way (I am assuming relay on GX is output only) I am attempting to read a ripple control unit to determine congestion and export under a special exporters contract I am setting up with my electricity retailer to get better rates than the generic spot price.
