server overrides Battery Charge Power

I had a Givenergy car charger added to my All in One installation earlier this week.
I had previously been able to set the battery charge rate below the 6kW maximum value.
I now find that whenever I set the Charge Rate through the app or the portal, my chosen value is shortly replaced by a max vale set by the EV Charger Inverter Control (see logs). I cannot find where to control this behavior.
Can anyone please advise?

After trial and error I discovered that, although the server overrides the Charge Power setting form the app, I can control the AIO batter charge rate by setting "Battery Charge Power Percentage" using Remote Control in the Portal.
This is the circumvention that I needed.
