Windows 11 Power Mode Question/Help

I have a Dell XPS 15 9510 w/ i9-11900H that I've done a thermal paste and pad replacement on a few months ago. Setting the Windows mode to "Power efficiency" reduces power and a modest turbo boost drop (but still some)...performance and temperatures are still good. However, I've noticed that when I plug the machine in, the Power efficiency is not in effect, machine runs at full power/speed, and machine still bounces off of 100C threshold even when doing simple productivity apps. I don't notice throttling but it still bothers me. Disabling turbo boost works and temperatures drop significantly, but there is also a performance hit. How come the "power efficiency" mode doesn't apply when plugged in and is there a way to enable it (or set maximum boost frequency) when both on battery or AC power? Thanks.

    Power Settings Explorer question. For 11th Gen and below I only need to enable and set Maximum processor frequency correct (i.e. all cores are the same)? For 12th Gen and above (with P-cores and E-Cores) I think Maximum processor frequency is for E-core and Maximum processor frequency for Processor Power Efficiency Class 1 is for P-core? I just want to double check.
