For setting groups (not ugp):

<options>
	<settinggroup name="productpermissions" displayorder="0">
		<setting varname="productpermissions_settingname" displayorder="1">
			<datatype>free</datatype>
			<optioncode>yesno</optioncode>
			<defaultvalue>1</defaultvalue>
		</setting>
	</settingroup>
</options>

displayorder="0" will hide the setting group from view in the vbulletin options setting groups display (unless debug mode is turned on).

For display of settings at the bottom of the ACP's links (cpnav_product.xml):

<?xml version="1.0" encoding="ISO-8859-1"?>
<navgroups product="yourproduct" master="true">
	<navgroup phrase="yourproduct_options" permissions="canadminsettings" hr="true" displayorder="10">
		<navoption displayorder="10">
			<phrase>vbulletin_options</phrase>
			<link>options.php?null=0</link>
		</navoption>
	</navgroup>
</navgroups>

For display of settings at the top of the ACP's links (admin_index_navigation plugin):

PHP Code:

if ($yourcondition) {
    construct_nav_option($vbphrase['productpermissionsphrase'], '../' . $vbulletin->config[Misc][admincpdir] . '/options.php?dogroup=productpermissions');
    construct_nav_group($vbphrase['productsettings']);
    construct_nav_spacer();
}
