Huawei P20 lockscreen hide content to all notifications

[Android Central Question]

So I have bought the Huawei P20 a few weeks ago and I've spent quite a few hours researching nice things I can do with it etc. but when I had Samsung S6, there was a way to hide all my notifications content on lock screen, whilst on Huawei all I found out is how to do it manually which makes it very annoying. Is there a way I can do it automatically for all notifications on lock screen to hide content.

For any reference, I am using Nova Launcher, I don't know if that can be done through there possibly don't think there is a setting for that there.

The only option on EMUI 8.1 is to allow notifications on lockscreen or not, you can not set how much information is displayed.
