You can access the application's preferences by opening the program from the icon in the lower right and then clicking the gear icon. From the drop down choose preferences.

You can make select changes to how the application operates, such as pointing it to a different drive letter or changing network settings so that it uploads at a different speed when on slower networks (it is advised to keep this on auto).

You can also add other Google accounts (including personal accounts) and switch between these accounts. Choose Switch account at the top to accomplish this.

Disconnect account removes the chosen account from Google Drive for Desktop.
