How to disable My Skills pop-up using CSS?

I’m aware that we can disable My Skills functionality completely to get rid of the pop up saying that you need to add your skills to your profile, however, the thing is… we want to be using My Skills - just without the pop up.

The unfortunate thing about it is that after you finish adding your skills, you get redirected to All Channels, which is also something we don’t want - especially for new users, who see this pop-up as the first thing after they log in and then get redirected to a page that is not even our home page (and is generally not in use).

Is there any way to disable this pop up using CSS or something else but without disabling the My Skills channel?
Thanks!
