K6000 plus fingerprint option missing

[Android Central Question]

Hello, my oukitel k6000 fingerprint option under security disappeared like it never existed.
I tried rebooting into safe mode
I drained my battery to Zero %
Boot into recovery
Also set pin security and deactivate then reboot my phone but none worked!
Help please, thanks
