Changing ConfigTDP (Down)

recently i came across the issue that when my dGpu starts running my cpu hang at 35W maximum while normally it runs at 45-50W i figured in my bios there is an option called configurable TDP power limit 1 (Down) gives 35W limit to my cpu to run i want to change this 35W value to 45W but i cant.
under its options i set power limit 1 to 75W and power limit 2 to 78W but actually they wont affect any thing the 35W is still the one working.
below there is a screenshot from HWInfo64 showing the configurable power limit at 35W.
if there is any way to change that value can you tell me please?
Below is attached screenshot form HWInfo64
