Cannot link X11 xQuartz 2.7.1, no architecture amd64?

There is a port of Xquartz to Apple Silicon - searching the web does give a few links

One I found https://github.com/XQuartz/XQuartz/issues/14#issuecomment-754400158 is by the person who maintains XQuartz

Yeah, it works fine and has since very early in our bringup of Apple Silicon Macs. There just isn't a package available because nobody has taken over managing releases, so your best bet is to use MacPorts.

and from https://forums.macrumors.com/threads/native-x11-support-on-apple-silicon.2274198/

X11 in MacPorts is functional and native on the M1. (I should know, I did some of the work to get it running.)

sudo port install xorg

MacPorts equivalent of Xquartz.app is X11.app.
