ALC is designed not to overdrive the final stage.
In the forum topic where the publication was made, it is described what you should do next.
A link is provided where the description of what to do is found.
This should definitely be done. It's not enough to just do part of it. But it is also written there.
If you haven't already checked the screws that attach the FETs to the heatsink, do it now.
It happens that during the transport these have become loose and therefore they are not clamped to the cooling fin.
So, if you have a good and solid hardware, you can modify the firmware and load the device.
You charge the device with this setting, but there was a delivery in between.
Even though the manufacturer has tested this, it may change by the time it reaches you.
