You can use the remove_meta_box function.

// Create the function to use in the action hook
function remove_vfb_dashboard_widget() {
	// Only run if the user is an Author or lower.
    if ( ! current_user_can( 'delete_others_pages' ) ) {
        remove_meta_box( 'vfb-dashboard', 'dashboard', 'normal' );
    }
}

// Hook into the 'wp_dashboard_setup' action to register our function
add_action( 'wp_dashboard_setup', 'remove_vfb_dashboard_widget' );
