PPD on Thinkpad P1 gen3 doesn't seem to do anything

Hello, on my Thinkpad P1 gen3 laptop, I see no change when I switch between the Power Modes in GNOME. powerprofilesctl provides this output:

$ powerprofilesctl 
* performance:
    Driver:     platform_profile
    Degraded:   no

  balanced:
    Driver:     platform_profile

  power-saver:
    Driver:     platform_profile

Whatever I choose, I see the same minimum a maximum CPU clocks during workload. The energy_performance_preference always says balance_performance, in all profiles, including power-saver.

$ cat /sys/devices/system/cpu/cpu0/cpufreq/energy_performance_preference 
balance_performance

I can compare this with my previous laptop Thinkpad T480s, where the power profiles had a big impact on the system. In the performance mode, the CPU clocks were always at maximum (never clocked down), and the energy_performance_preference changed between power, balance_performance and performance. The powerprofilesctl output said Driver: intel_pstate.

I'd like PPD to work on my P1 gen3 similar to how it worked on T480s. Perhaps it is using a wrong driver and should be using intel_pstate even on P1? Thanks for your help.
