You have full control to set this level anywhere from 0% (completely off) to 100% (no dimming at all).
Remember, you need administrator privileges to modify this power-saving feature.
Change keyboard backlight brightness in Windows 11 Energy Saver mode by editing the Registry Editor. Navigate to 🗝️HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Lighting\Backlight, find or create BacklightEnergySaverMultiplier, and set its value to your desired percentage (0-100).
