Disable Right Column from Home Page

Hi I am working with Audioman Free theme. I want to have a blog (posts) page with a right column, and a static home page that does not display posts and without a right column. Ie. The home page and post pages are different pages. Once I specify a page as my post page, the layout options are overridden. This does not seem possible in Theme Customisation either. The options are to have a right column everywhere, or nowhere. Is there custom CSS that I can use to disable, or enable on the page I want. Any advice appreciated.
