Can't enable P-States on ryzen 7 4800h

Hi People.
I don't know jack sh!t about python.
People are telling me it is not possible to undervolt the ryzen 7 4800h chip.
I would like to know if you fine people would kindly provide the info;
- how can I enable the remaining P states? (only 0, 1 and 2 work)
- what values am I supposed to use to set a voltage for a p-state?
- and is my chip even supported in the first place?
I would really appreciate any useful intel.
Thank you.
Edit: I am on an XMG core 15 (equivalent to eluktronics rp 15) and my goal is to squeeze as much battery life out of my system as possible.
I am in no way any more clever in this than you are, but as far as my understanding goes, the lower the P state, the higher heat and performance at the cost of battery life.
...And I am facing the same issue of not being able to get higher P-state.
but for overclocking I thing there is something in the kernel params you must enable first to unlock the full control
btw you can change the values, but not with zenstates, rather with kevinlekiller/amdctl#40
The program works well and this issue showed me how to monitor the stuff.
For me lowering the voltage works, but if you want to get to lower p-states you must crash the higher ones, like with setting it to higher frequency than specified by the vendor.
