Assuming of course the M1 doesn't have SoC code to zero day your proxy server or zero day your OS and selectively allow itself to circumvent this. But if Apple were really clever they'd add a secret undocumented radio built into the SoC package that sends signals modulated in an unusual way over an unusual low-bandwidth but high signal frequency (probably sub-CB Radio) that no one is monitoring. Which now brings you to the scenario that you have to use a machine that not only never uses a network, but also exists in a physical place that no network signal could ever penetrate. And it goes without saying that having taken this level of caution, one should probably buy the computer with a fake name and all cash, ideally through a network of international proxy buyers, to be sure.
