Passcode not in ios 11.1

Hi, I got new iPad Pro and I want to protect it with pass/pin/gesture/whatever.

However, I miss any option how to do that.

After first boot, Touch ID didn't run, just throwing a messagebox that "it is no longer available".

So I run a software update, now running on iOS 11.1.

Now, Touch ID shows black and then crashes at all. But that is only Touch ID, my problem goes further. There is no other option of setting password.

I have searched a little bit as I am new to iOS, so if I have missed something, but it seems there should be a "Passcode" option in menu.

Also didn't find anything under general options, nor Account and passwords, nor Privacy, nor in other apps like link to Touch ID settings.

Also this happens in English and my native language, so this is probably not something related with translation missing that results in whole item missing.

here is an image from my settings:

(sorry for no direct link, apple blocks it 😟 )

So, please, any advice, how to reslve this?

Thanks in advance
