that is not possible, instead run these commands locally with railway run that runs the command on your computer, but makes the environment variables from your railway service available locally

As I am using private link in production to connect with db.

I am trying to run a local file (to inject some data into the database). That will not possible work while running the command locally.

Is there any workaround for this?

but that didn't seems to work either.
