Disable right sidebar on Home page

Hi support, I want to disable the right sidebar on home page. I have tried the obvious filter within functions.css but apparently I do something wrong. Please see the site.
You see two sidebars, one within BeaverBuilder and the sidebar at the far right I want to have disabled.
I use:

add_filter( 'generate_sidebar_layout','tu_custom_category_sidebar_layout' );
function tu_custom_category_sidebar_layout( $layout )
{
 	// If we are on blog page, set the sidebar
 	if ( is_home() )
 	 	return 'no-sidebar';

 	// Or else, set the regular layout
 	return $layout;

 }

Thanks!
