You could set the environment variable in the settings file as explained in below link.

> One way of setting environment variables is in your settings.js file. The following will set the env var MY\_ENV\_VAR: process.env.MY\_ENV\_VAR = "Hello World"; You can add lines like that to the top of your settings file. The other option is to set them completely outside of Node-RED in shell you are running Node-RED in. How you do that will depend on your OS and how you are running Node-RED.
