HP omen 16-c0500 with Ryzen 5800H exceeding 100W

While under high loads (e.g. gaming) the cpu power as reported by HWInfo64 and also by rivatuner regularly excedes 100W and stays arround 90-140W for the entire gaming session. (see photos below) The Ryzen 5800H has a TDP of 45W and in reviews of laptops (including other hp omen 16s) using the same CPU, they are usually limited to around 65W for anything other than a few seconds. I have a very simmilar cpu in my desktop ( Ryzen 5700G) which usually has less than half of the power draw in the same applications despite being the higher TDP desktop chip based on the same architecture. I have tried updating to the latest bios and made sure all drivers are up to date.

As you would expect, the cpu usually reaches 90-100 degrees C with the fans on 100%, often even with only 30-40% CPU utilisation.

I am experienced in overclocking/undervolting and would ideally like to leave the cpu without any power constraints but with a negative voltage offset to reduce power consumption and temperatures however i have not been able to access the advanced BIOS or to use software such as Ryzen master to adjust the cpu voltage outside of the BIOS.

Does anyone know how i can access the full advanced BIOS on my model of laptop? i understand that this could potentially allow me to damage my laptop if incorrecly used, however i only intended to undervolt the cpu which cannot cause any damage to the cpu, and if anything will increase its lifespan by allowing it to run at a lower voltage and temperature.
