From your theme options go to the Footer tab for the basic footer setup.
At the bottom of each page the theme defaults to show the widget area and below that the “socket” which shows the copyright field and sub menu if you choose.
This dropdown allows you to change the default display to show one or the other and even none at all. Can be changed on individual pages from the Layout meta box
The Footer of the site can hold up to 5 columns which can be populated with widgets. Select the number you wish to display, save and then go to Appearance>Widgets to add your own choice of widgets to replace the default widget items.
If you want to simply clear the default widget from showing just add a blank text widget to that columns widget area.
