Remove TP from the help tab. If I've got this right, it's in Sources\TPassimilate.php
Look for, and change true, to false at the bottom.
// Add the help
if(array_key_exists('help', $buttons)) {
$buttons['help']['sub_buttons'] = array(
'tphelp' => array(
'title' => $txt['tp-tphelp'],
'href' => $scripturl.'?action=tpmod;sa=help',
'show' => true,
),
);
}
