Manifest editing possible or not?

I’ve checked the AndroidManifest.xml and didn’t find that option. I found the android:usesCleartextTraffic="false"

Cleartext traffic - Pre-Launch Report Security & Privacity

Note: Starting with Android 9 (API 28), cleartext support is disabled by default.

So why you should this be found in the Manifest?
android:usesCleartextTraffic="false"
