Locking screen immediately

[Deexterity]

Hey guys, I'm running latest beta on my Mi 8 Lite and when i lock my screen I have to wait 5 seconds to really "lock the screen" if I don't wait and press the button again I get to the same screen I was before locking... Is there a way I can lock my screen immediately as soon as I press the power button ? I can't seem to find that option in settings
