Undervolt seems not working on i7-12700H at Lenovo P15v G3

[xtermi2]

It seems undervolting is not working. I use the latest master and I configured

[UNDERVOLT.BATTERY]
# CPU core voltage offset (mV)
CORE: -30
# Integrated GPU voltage offset (mV)
GPU: -10
# CPU cache voltage offset (mV)
CACHE: -30
# System Agent voltage offset (mV)
UNCORE: -10
# Analog I/O voltage offset (mV)
ANALOGIO: 0

# All voltage values are expressed in mV and *MUST* be negative (i.e. undervolt)!
[UNDERVOLT.AC]
# CPU core voltage offset (mV)
CORE: -70
# Integrated GPU voltage offset (mV)
GPU: -50
# CPU cache voltage offset (mV)
CACHE: -70
# System Agent voltage offset (mV)
UNCORE: -50
# Analog I/O voltage offset (mV)
ANALOGIO: 0

and logs of throttled.service seems OK:

but ./throttled.py --monitor shows no undervolt offset:

any suggestion?

Intel 11th and 12th gen processors do not support undervolting at all.

Thanks @neil1969 , but that's a shame.
