Wine will just use the GPU capabilities of the Mac by mapping DirectX/3D calls to Metal. No need to keep any Windows installation, ever.

Also here we are running Amd64 (64 bit Intel, but I use Amd64 for the original architecture) games into ARM with the translation layer. It might have a performance penalty but most WIndows games are Amd64/i386 CPUs anyway.

The video link I gave to you it's a guide to setup Windows' Steam release under MacOS+Wine. Once it's installed you just click on the launcher and that's it, Intel PC Steam under your Mac.
