Does Logitech Gaming Software qualify as a driver?

The Logitech website describes their Gaming Software as a configuration utility. Is this the same thing as a driver?

I use the programmable buttons on a Logitech G602 mouse to replace several keyboard shortcuts. I'm trying to get LGS installed on my work computer. I'd just do it at home, but my work computer is a PC and my personal computer is a Mac. Programming my mouse on it doesn't always translate over.

Tech support is pushing back, saying that they don't install "third-party drivers", but I'm not sure that LGS qualifies.

I hope this isn't a silly question. :/
