You probably figured this out already but just in case you/others
The easiest way is to go to Administration -> Dev Tools section 1/2 way down -> Display modules and sub panels
Drag over the ones you want to hide.
Unfortunately, Direct Reports isn’t one you can control, even if you never us it, like us.
I suppose no one have figured out how to do so maybe w/o affecting some sales process/dependency?
So you will have to comment that out. Can someone direct us where? I would like to remove it also as we don’t use it.
