15 R4, Windows 11 and Bios updates

Hello,

I am hoping to resolve what appears to be an AGE OLD issue of the display not switching back on after the laptop has gone to sleep. One part of a solution I found was to update the BIOS.

While I could see there is an update available, Dell does not include Windows 11 as a supported OS! I was somewhat staggered. Will Dell be supporting Windows 11 for Alienware devices such as mine?

I am not sure if I am risking all by updating the BIOS. Perhaps I should not have upgraded to Windows 11  

Any advice?

Thank you.

Steve
