Next.js: How to disable telemetry permanently in all environments? - next.js

Question

I want to disable Next.js telemetry in all environments, forever (Just because, Ok? Let's not sidetrack the question with irrelevant debate).
I don't want the telemetry to run on developer environments, test builds, CI builds or anywhere else.
I'm trying to find a "code" solution - I don't want to have to do anything manually in an environment in order to switch off telemetry.
Next.js makes it difficult to figure out if telemetry is enabled because it only prints the telemetry warning once on a given machine.
My diagnostic for knowing if telemetry is running is to add the next telemetry status command to my build script in package.json:
"build": "next telemetry status && next build",
I've tried adding the following to next.config.js:
module.exports = {
env: {
NEXT_TELEMETRY_DISABLED: '1',
},
}
And I've tried adding this to .env:
NEXT_TELEMETRY_DISABLED=1
But the telemetry command still reports Status: Enabled
In fact, the NEXT_TELEMETRY_DISABLED env variable doesn't seem to work at all, I tried manually disabling telemetry in my IDE by setting the env variable, but it still reports telemetry is enabled:
Next.js version: 9.5.2

Adding next telemetry disable command as my prebuild script seems to have done the trick.
"prebuild": "next telemetry disable",
"build": "next build",
