AceLan Kao,
     Going the HP support route we all know will be extremely painful, if, I 
can convince their support to forward my query along to the right people.

Is there no method to debug or expose the reason for the failed PPM init and/or 
what the GPE17 triggers are called from?
I am assuming if I go back to Windows 11, the cpu is calm and the interrupts 
are not happening.
I am also assuming the issue to be that whatever the triggers are, the response 
is not expect or not happening, therefore the triggers continue.

I found a similar bug that mentions the unloading the ucsi_acpi module.

Bug 217076 - Charging causes high CPU usage on LG Gram laptops series Z90Q

I would like some help identifying if it is similar in nature since that
patch was very specific to those LG models.
