I'm sure it's possible, depending on the kind of application and the tools you use to build it. But xcode won't build your application if you don't link your account. I believe it needs that to "sign" the application with apple.

There may be ways to get around this but I don't of any.

You can manage your signing identity entirely using Apple's website and just not use automatic provisioning. (I do that anyway even though I build on macOS as I just don't want our build system tied to Xcode just so we can use the automatic provisioning.)
