This tutorial shows how to hide the icons of mounted drives / partitions from the left (or bottom) dock launcher in Ubuntu 21.10 and / or Ubuntu 20.04.
When you plug in a USB drive or browse through an external system partition in Nautilus file manager, a new device icon will appear in the left dock panel in Ubuntu Gnome desktop.
To keep your panel clean, you may remove these removable device icons and prevent them from appearing again. And this can be done either by running a single command in terminal or using a graphical configuration tool called Dconf Editor.

1.) Firstly, open terminal either by pressing Ctrl+Alt+T key combination on keyboard or by searching it from the Activities overview screen.
2.) When terminal opens, copy and paste the command below into it and hit Enter.
