intel-undervolt VS throttlestop

10th gen is locked by "Overclocking lock" And "Cfg lock" in bios, you can disable it thru ifr and use any software to undervolt your cpu (throttlestop on windows, linux has its own software (this, probably)). This is a lot safer than just putting voltages in bios as you can guess.

On Windows machines and laptops with Intel cpus, I almost always use Throttlestop to tweak power consumption and thus temperatures. I'd like to do so on this machine as well. I've found this: https://github.com/kitsunyan/intel-undervolt

intel-undervolt - though I may not be using this optimally. CPU: -75, GPU: -50, CPU-Cache: -75

You can use intel-undervolt to modify the voltage, TDP.

I will try your suggestion about limiting power package. I've been using this 3rd party intel-undervolt software, which I'm not sure if it supports granular changes to wattage, but it seems like there is some energy/performance settings there.

I personally use intel-undervolt and auto-cpufreq.

You can also undervolt though software on Linux based OS's. For intel there's these: https://github.com/georgewhewell/undervolt (this one looks more popular) https://github.com/kitsunyan/intel-undervolt (this is the one I use, no particular reason)

intel-undervolt also works fine for Intel laptops (I've used this successfully with my 11th gen H laptop).

Throttlestop - https://github.com/agoose77/throttlestop

Use a cooling pad. Use throttlestop to limit power thus stop throttling by high temperature. https://github.com/agoose77/throttlestop

There are tools for Linux for undervolting, but they are all commandline. This might be a dealbreaker for you, but is really not that bad. For many folks, it's much simpler than all the clicking. The tools are throttlestop for linux and undervolt.
