RTX 2070m Power limit/target unable to be set. Is there an Alternative?

I would like to set the power limit/target of a RTX 2070m in order for it to operate at acceptable temperatures. At the moment, even under moderate workloads, such as a game, limited to 30 FPS, the GPU throttles all the way up to 100 degrees Celsius and then shuts down. This behavior is not exhibited when using windows. In an attempt to remedy this, I execute nvidia-smi -pl 30, which errors out with the message

Changing power management limit is not supported for GPU: 00000000:01:00.0.
Treating as warning and moving on.
All done.

From what I have read, this functionality is implemented per-device and comes down to hardware, so I’m out of luck here. So, I would like to ask if there is a way to do something similar to this. I suspect there must, since PowerMizer seems to be making a conscious decision about clock frequencies, etc, on the cpu side. Until I find a solution, the card is effectively useless.

Versions of installed nvidia utilities & NVIDIA log:

    NVIDIA drivers utilities (32-bit)
local/libvdpau 1.4-1
    Nvidia VDPAU library
local/libxnvctrl 465.27-1

    Tool for configuring the NVIDIA graphics driver

Any and all help is appreciated.
