Enabling CPPC

Has anyone managed to boot their device with CPPC enabled? I wanted to try running the amd_pstate driver for cpufreq since lscpu | grep cppc shows the CPU has support for it, but going in the (unlocked) UEFI to AMD SCB > SMU Debug > SMU Features > Enable CPPC leaves my unit stuck on the Deck logo at boot...

Edit: I forgot to mention that I had also enabled AMD CBS > CPU Common Options > Global C-state Control.

Looks like I'm not the only one having issues on this, a Bazzite blog post speaks of "issue with CPPC in the Steam deck's firmware" making them unable to use the amd_pstate driver.
