It might be interesting to test if changes in this area via KDE persist with the switch to game mode. Much of what you do in KDE is just making changes to much lower level system rules, so you may find you can set rules in KDE and use them in Steam.

Don’t know if it’s possible with SteamOS. But in KDE you can select different power profiles for battery powered and on a power supply. And those profiles can be configured.

Sadly I don’t think you have these in gaming mode.
Maybe in desktop mode though since Steam OS uses KDE.
