How to dynamically update configuration property in YAML file using node.js application

Question

I want to update the attribute dynamically in YAML configuration file using node.js application. I have my secrets configured in KeyVault and it has been referenced in App Service configuration. I want to update those secrets in YAML file through node.js application.

I tried below option in YAML file, but it's not working.

#{process.env.password}

My YAML structure looks like,

targets:
  - host:
    ssl:
      client:
        password: XXXXXXXXXX (I want to update this password attribute using environment variables)
