CentOS - Jan 2017 - Centos7: disable hot-corner

Hello All, 

I switched some laptops over from Mate to Gnome. 
Now I would like to disable the hot -switch-to-gnome3- corner. 
When googling this, I see a lot of posts referring to /usr/share/gnome-shell/js
/...... but the js dir is not there on my system.
I also see posts referring to gnome-extensions, but I need to do it remotely
from the cli.

Can anyone help with this? 

Greetings, J.
