Unlocking max power on i7 12800H

Question

I have an i7 12800H processor that should be boosting to over 100W of power, but it never goes above 45W as per turbostat. The fans of the computer don't even spin up.

This is what I get from powercap-info intel-rapl:

The power limits look OK, those are the correct values (65W and 160W).

The problem seems to be on the max_power_uw: 45000000 line of the constraint 0. I can't change that one, and seems to be limiting the power regardless of the power limits.

I've seen a lot of posts about changing the power limits, but in my case those are correct. I don't see anything about that max_power_uw.

What can I check?

Update

I have another laptop with an i7-1165G7 where PL1 is 35W but max_power_uw is 28W, and this one does boost to 35W without problem, so max_power_uw is not what is stopping the 12800H from boosting, it has to be something else. Here is the powercap-info output:
