How to define process.env.ENV in create-react-app?

With the version 1.0.5 of the create-react-app boilerplate I've started receiving the fallowing warning: *** process.env.ENV is not defined, assuming 'prod' env

I know how to create a custom environmental variables, but those require REACT_APP_ prefix.

Now, I've discovered that the message is being shown because of the Chrome's Grammarly extension, and disabling it removes the message.

However, I'd like to know how I can resolve this regardless of the extensions.

I know that there are 2 more questions like this on the StackOverflow, but they include solutions that are using the Webpack. Unfortunately, I have no access to the Webpack, since I haven't ejected the create-react-app, and I don't plan to anytime soon.

Is there a way to declare the environment on process.env.ENV in create-react-app?

EDIT:

This was the main question. Is it technically possible to define it in the non-ejected create-react-app?

The Grammarly extension is the cause of this not React. Have logged a request with Grammarly Support and this is the result

Unfortunately, this will not be a quick fix and I cannot provide you with an estimated timeframe, as the developers will need some time to analyze the cause of this issue.

The console window in Chrome is constantly showing the warning - "process.env.ENV is not defined" turning off the extensions removes the error, it is not related a specific website. Already on the internet threads are popping up with people reporting the same issue and the common thread is Grammarly. Has a bug been introduced into the extension perhaps?
