H570M-ITX/AC does not reduce voltage when idle

   Hi Folks!
i7-11700K on H570M-ITX/AC does not reduce cpu voltage when idle. I have tried each combination of C1E/EIST/SpeedStep/SpeedShift/Turbo parameters in UEFI. At stock speed 3,6 GHz it still keeps ~1.000 V does not matter if idle or load.
In my other setups with Asrock Z270M-ITX/AC and Z270M-ITX/AC Gaming, there is no problem with that - even on performance power preset cpu reduce voltage down to ~0,6 V when idle keeping 3,6 GHz frequency. Same situation on bios version 1.30 and 1.50.
There are lot of cpu-z screen shots in the internet with ~0,6 V for i7-11700K so looks like problem is with my motherboard.

I see there is new microcode (50) for cpuid 0677 - maybe new bios release could fix this issue ?

Thanks in advance for any help.
