Can I change my Alcatel Idol 4S Windows 10 to Windows 8.1

How do I install Windows 8.1 on an Alcatel Idol 4S Windows 10 phone? I bought it new with Windows 10 and it is nowhere as good as my Microsft 640 with 8.1.

You got to be joking right? Many apps and features are no longer supported in Windows 8 phones. also Win 10 Mobile gets support and updates until December 2019. Your current Win 10 Mobile is a pretty decent high end Win 10 mobile. What is wrong with it?

Sadly this is not possible. I also want to know, what don't you like about W10M? Can you tell us?
