This can be remove by using a filter. Install the Code Snippets plugin and add a new snippet with the following code:

function cn_remove_family_entry_type( $atts ){

    $atts['entry_type'] = array(
        __( 'Individual', 'connections' ) => 'individual',
        __( 'Organization', 'connections' ) => 'organization',
        );

    $atts['default'] = array(
        'type'       => 'individual',
        'visibility' => 'public'
        );

    return $atts;
}

// Filter to limit to the organization entry type.
add_filter( 'cn_metabox_publish_atts', 'cn_remove_family_entry_type' );

*Save and Activate the new snippet to run everywhere.

Hope that helps!
