disable the encryption on stock rom 7.1.1

[cicci0]

hi, I unlocked and rooted my nexus with 5x stock rom 7.1.1

I try to disable the encryption of files by formatting the data partition, but if you check in the SECURITY settings, the phone is always encrypted.
What am I doing wrong? Thank you.

Decrypt Question

Are you flashing SuperSu to patch kernel to remove forced encryp or flashing a custom kernel to remove it? If not, the stock kernel will re-encrypt upon boot.

I think that is normal, mine also shows encrypted currently with a stock kernel. Only time I need to decrypt is in TWRP, and instead of a password, I'm using a pattern.

That's probably not the kind of decryption he was looking for.
The correct answer has been given

thanks for the answers, but I still have the same problem.
I rooted, I installed the latest TWRP recovery, as well installed nexus ...
Then I formatato the DATA partition.
Start the well nexus (latest version) and under the heading Safety, the phone is still encrypted!
The kernel of pure nexus is stock?
