There are many posts explaining how to enable the DPM (dynamic power management) feature of AMD GPUs. I need to do some testing and require to disable it but I'm not sure how.

For Radeon driver, I read it is required to modify /etc/default/grub, by setting

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.dpm=1".

May sound obvious, but would it be enough for AMDGPU to do something like this?:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.dpm=0"

Depending on what you want to test, you can also disable bapm for example.

See the full list of boot parameters for amdgpu and their explanation here.
