Probably, with the help of ASPP-Override.kext.

I found a guide about enabling pm in Ventura and follow it but some parts in the guide im not sure about like if my mobo has CFG look or not ? I did check in bios but didnt find it so what should i do ?

Also about this part ( Booter/Patch: Add Booter Patches from OCLP to skip board-id check to run macOS on unsupported SMBIOS/Board-ids. Requires )
Im not sure what to add to the config file and or if just adding -no_compat_check would be enough or does that not work in opencore just clover ?

When i did command ( sysctl machdep.xcpm.mode ) i did get 0 in return but when i did (
kextstat | grep com.apple.driver.AppleIntelCPUPowerManagement )
it didnt work and gave me some error.

Here is the error,

as you can see, core max is wrong and should be 3.8ghz, and core REQ is stuck at 3.2 when it should go up and down like it does in El capitan for example.
