How can I hide the navigation bar?

I have a Huawei Y7 (Emui 5.1) and I feel the navigation bar sometimes very annoying. You can somehow disable it somehow? I did not find anything on the internet.

For P10 lite:

Settings → System → System Navigation

try it

You have 2 options

1 You scrounge from top to bottom and turn it off

2 you go to settings and disable it
