Example Code

@app.command(short_help="Creates Secrets")
def create(
    name: str = typer.Option(None, "--token-name", help="The name of the token."),
    auth: str = typer.Option(
        None,
        "--auth",
        envvar="AUTH_TOKEN",
        help=".....",
    ),
    config: Optional[Path] = typer.Option(
        None,
        exists=True,
        readable=True,
        file_okay=True,
        resolve_path=True,
    ),
):

Description

In the above example function definition, is there a way to make the argument environment variable auth key envvar="AUTH_TOKEN" to be defined by the user instead, rather than hardcoding AUTH_TOKEN ?

Have you considered changing your command's API to take an environment variable name as an option and then read from that environment variable internal to the command? That seems like the clearest way to do things. I don't think you could otherwise make one --auth option mean two different things cleanly.
