Planning for negative feed in

It’s going to come where FIT will be in the negative atleast for part of the day. It’s already negative for wholesale providers amber electric etc.

Are you able to curtail a fronius symo inverter? Would you set the export limit to 0?
Is there a way to be able to do it via api or remotely?

Or what can be done to mitigate the amount of power you feed into the grid?
