A way to not propagate certain env vars to devices?

Some of the HTTP and proxy routes we have use access tokens in HTTP headers, which will be rotated routinely.

I understand we can use [$ENV_VAR] syntax to substitute environment variables in the header value. However, the token is sensitive information, which we don’t want to be available to Notecards in the project.

Is there a way to code an environment variable so that it is private to the project and not shared with devices?

Thanks!
