You can copy the FEX dll (libwow64fex.dll) into the windows/system32 directory, and specify the dll name in the HKLM\Software\Microsoft\Wow64\x86 key.
Your Wine also needs to be built with i386 support, i.e. configure --enable-archs=aarch64,i386.
I would add that documentation into the readme for compiling wine for Arm64.
Alrighty so I got Wine compiled properly but I can't find proper documentation on how to compile Fex and get the dll files compiled, I found some documentation on their wiki page but I don't know if it's outdated or not since it's got different compiling instruction it doesn't recommend using
