The only global options are in Theme Options-> General -> Layout Style and Theme Options -> General -> Layout Width
For every page, there is a full-width check box at the end of the editor. This full width is full width of the Layout Width selected in theme options, not 100% span across the browser.
There is no full width template in Evolve Plus theme.
If you require anything that is not available and cannot be done using a few Custom CSS, you can contact as for a quotation for theme customization at our service page. https://theme4press.com/services/
