Then instead run it as a oneshot .service with StandardInput (and maybe
TTYName) set appropriately. (It's one of the few situations where it is
appropriate for services to access a tty.)

I think such settings *could* be made part of vconsole.conf, though. Try
opening a feature request on systemd's GitHub.

It's implemented by the "graphic mode" itself (usually by Xorg), not by
systemd.
