m15 R5, installed Windows 11, the display is dim

I have the 240Hz refresh rate LCD with 400 nits of brightness. After installing Windows 11 the display brightness is dimmer. I have tried more than one Windows 11 installations but my LCD is still dim. Does anyone know when will Dell fix this because after searching on the internet this is caused by Dell provided drivers intentionally limiting the max brightness of the screen for Windows 11. I have no problems with Windows 10, my laptop LCD is really bright.
