Disable Unity Dash icon (BFB)

I kept searching the Internet up and down for a way to do this. Basically, I want to completely hide the BFB (Big Freaking Button), aka Dash icon, aka ‘search your computer’ icon from the Unity Launcher, so as to have the dock look more like the GNOME counterpart.

I am using 19.04 with Unity for a lot of reasons (proper high DPI scaling being one of them) and do not intend on switching to something else. I am actually in the process of patching minor aspects of Unity and use it for as long as I can. I am fine editing and recompiling the source code for ‘unity’, I am just asking for a pointer to what to actually change so as not to keep browsing the whole source code looking for it.

Thank you very much.
