MultiPostThumbnail only in custom template page (metabox)

[enlego]

I have several pages: About-us, Home, Proyects, etc. When I use the function

if (class_exists('MultiPostThumbnails')) {
    new MultiPostThumbnails(array('label' => 'conocenos','id' => 'imagen-conocenos','post_type' => 'page'));
    new MultiPostThumbnails(array('label' => 'Imagen 2','id' => 'imagen-2','post_type' => 'post'));
    new MultiPostThumbnails(array('label' => 'Imagen 3','id' => 'imagen-3','post_type' => 'post'));
    new MultiPostThumbnails(array('label' => 'Imagen 4','id' => 'imagen-4','post_type' => 'post'));
    new MultiPostThumbnails(array('label' => 'Imagen 5','id' => 'imagen-5','post_type' => 'post'));
}

the first one post_type=>'page' is showing in every page. How can I enable it in Home but disable it in About-us, Proyects, etc?

Thanks in advance!

Hook a function in add_meta_boxes with a higher priority than 10 and remove_metabox with the id of page-imagen-conocenos with a context of side on the page if its the page you don't want it on (or not the page you want it on)...

Thanks matgargano. I'll paste the solution here in case someone else needs it.

// Add the following code at the end of functions.php
// remove MultiPostThumbnail for pages not using the template page "tp_conocenos.php"
add_action( 'add_meta_boxes', 'remove_img_metabox_conocenos');

function remove_img_metabox_conocenos() {
        // get the post id to check which template is usign.
        $post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'] ;
        $template_file = get_post_meta($post_id,'_wp_page_template',TRUE);
        if ($template_file != 'tp_conocenos.php') {
            remove_meta_box('page-imagen-conocenos', 'page', 'side');
        }
}
