Huawei honor 9 lite?

I have the Huawei honor 9 lite and can't lock a lock pattern but only a lock pin is normal would rather have a pattern

What do you mean by "can't"?

Well man usually when you want to lock your cell phone either

Pin code

template

Select password but I can only take a password on my cell phone and I would rather have a lock screen pattern but somehow it doesn't work?
