[SOLVED] Proxmox Kernel - how to enable ACPI?

[Peam269]

Hey there,
My machine is running 7.2 VE and I want to fully disable my dGPU by using an ACPI call to benefit thermals and power saving.
Though, when installing acpi-call-dkms the acpi_call module won't get built. The error states the following:

ACPI disabled in this kernel, not building module.
Building for 5.15.39-4-pve
Module build for kernel 5.15.39-4-pve was skipped since the
kernel headers for this kernel does not seem to be installed.

Can anybody help me out here? Thanks in advance!

Here I had to manually install the headers: apt update && apt install pve-headers

I think you meant arrogance. And, i think that I have clearly stated what I want to do in my first post, you'll just have to read it carefully
