Where is the setting << Keep phone unlocked when in hands>>?

[Brjlk]

When I was doing some settings, a Google pop-up window appeared asking me if I want to keep my phone unlocked as long as it is in my hands:
-No
-Yes, I am in.
And I entered Yes

I have been looking for that setting since that & cannot find. Don't know if it is an Android setting or Nova Launcher setting. Any one knows? Thanks

Thanks a lot.

However the setting does not always prevent the phone from locking. Maybe Nova or Greenify is interfering.
Anyway this feature is not very important & has some security issue.
