Just don't clamp it so near.
You need to run something like Cinebench for 30 mins, look at your power draw, and set Short Duration limit above the highest power draw, and Long duration limit above the lowest power draw.
I usually use a mindful +2W on each lowest and highest Maximum power draw in HWi info and then round that up to the next 0-5. So if I see something like 54.595W lowest and 66.388W on highest, I'll use 60W for Short Limit and 70W for Long Limit.
Reason for that is that modern CPUs basically overclocked OTB to still promise something and get some market, they live in a tight box. In a long enough setting of load, power will creep up as temps will creep up A BIT because indeed voltage will likely creep up A BIT.
You won't burn your CPU. At this kind of power, you'd likely see +1-2*C max running Cinebench a few times in a row. For this you're likely to see it running something like 2-3W above the highest you got in a single test as well.
In a laptop, cooling is so constricted that I wouldn't be surprised you'll need to up your Short Duration limit much closer to your Long Duration limit, contrarily to what I see in your settings. However, if 30 mins Cinebench sees only 66.272W of highest power draw, don't use 90. Limit the worst that could happen by setting 70W.
