Question on power management in laptop

Hi,
I have recently changed to a new Nvidia powered laptop with a RTX 4090. And I’m running ubuntu noble with default drivers (550.120).

I installed nvidia-powerd to avoid only having 30 watt power limit on a 175 watt gaming laptop.
Nvidia-powerd works most of the time however sometime it get stuck at 33 watt and for the moment the only way to fix the issue is to reboot which can be annoying when experimenting gpu based ML code.

I would like to understand better how the power limit is set. How to override it when I’m running ML code and need to use all the power of my laptop. I originally tried to override using nvidia-smi but it seem this feature was removed.

Personally reability of beeing able to use all the power of the GPU when needed is more important than reducing power consumption or noise. Having a easy override when the dynamic system fail would be nice.

I would like any pointer on detail information about powerd and nvidia power usage.
