BIOS Settings

Is the Aptio Setup Utility by EaseUS legitimate? What I mean will it trash the BIOS that is running now or is it a tool I can use to change the BIOS settings easier as all the instructions that I have seen none of them have the same menus that is on my DELL XPS 8930 Tower? I am trying to install Linux and dump Windows and not look back.

Anyone that has used this I would greatly appreciate hearing from you.
