The thing is if your laptop cpu is getting really hot and you are trying to undervolt it then chances are 99% that there are no method to do so. I have also tried to do undervolt my Ryzen 7 5800H but no luck. Because the bios doesn't allow that much control over the cpu. I don't know the specific reasons for the manufactures to restrict such a great thing. But with this you can disable the Turbo Boost. While this might sounds stupid but trust me you won't see a massive difference in performance after turned it off.
- Your laptop has a really powerful CPU.
- The work you do with the laptop is mostly
GPU dependent. - You play games and those games are
not CPU dependentor moslyGPU dependent.

Before I tell you about all the states/modes you need to know a few things.
CPPC is a newer method of performance control defined in the ACPI (Advanced Configuration and Power Interface) 5.0 specification. It allows for collaborative communication between the operating system and the hardware to manage the performance of the processor. With CPPC, the operating system can dynamically request specific performance levels from the hardware, including enabling or disabling Turbo Boost. This method provides more fine-grained control over the performance of the CPU.
P-state is an older method of controlling CPU performance that has been used for a long time. It involves a predefined set of performance levels, also known as P-states, that the CPU can operate at. Each P-state corresponds to a specific frequency and voltage combination. The operating system selects the appropriate P-state based on the current system load and power management policies. However, the P-state method does not provide as precise control over CPU performance as CPPC.
Intel Turbo Boost and AMD Turbo CORE technologies are features that allow processors to achieve additional performance during high system loads. However, they increase CPU energy consumption.
In Windows, Turbo is enabled for High Performance power plans on all Intel and AMD processors, while it is disabled for Power Saver power plans. For Balanced power plans on systems using traditional P-state-based frequency management, Turbo is enabled by default only if the platform supports the EPB register.
For Intel Nehalem and AMD processors, Turbo is initially disabled on P-state-based platforms. However, if a system supports Collaborative Processor Performance Control (CPPC), Turbo may be engaged if the Windows operating system dynamically requests maximum performance levels.

OK, if you've enough patience to read through all those now follow the table below to choose the option you want and if you haven't, to disable boost mode just choose
