m15 R5, cannot adjust my brightness level, #2

Hi,

I've found similar issue from other conversation, although they provided some alternatives, it makes one thing fails another.

If I downgrade the driver, I could not run local LLM. If I disable in the bios, I lose AMD Radeon Graphics. Can Dell please fix this issue properly? I'm very disappointed with Dell's faulty hardware and software issues on this specific device (m15 R5). I spent hours and hours on a machine which should be useful for doing my business stuffs instead of troubleshooting device issues.
