Can I disable the "remote control" feature of SmartSolar RX pins?

I have two SmartSolar MPPT controllers connected via ve.direct to a homemade circuit. If my circuit pulls the RX pin to ground, by default the controllers will interpret that as a "remote control off" and disable charging.


Can I change this behavior? on one of the controllers I can set the RX port to control load output, and that works for me because I am not using the load output; but the other one does not give me that option (since it has no load output).


I tried disabling remote control via ve.direct - through register 0x0202 - but the devices appear to ignore my requests to update that register (they will accept and reply successfully to the command, but the register value does not change).
