Hi,
I would recommend keeping the clicks popup and just removing the IP address from the table there.
Because first, if you remove the link to the popup, technically, someone could still access the URL of the popup to get the IP addresses. And second, besides the IP addresses, I think it's quite useful for the partner to see the clicks when he adds the banner on his website and doing tests, to make sure it's working fine.
To just remove the IP addresses from the popup, you can edit the file affiliate / clicks via the menu Display>Views and remove:
<th class="title">
<?php echo JHTML::_('grid.sort', JText::_('IP'), 'a.click_ip', $this->pageInfo->filter->order->dir,$this->pageInfo->filter->order->value ); ?>
</th>
and:
<td>
<?php echo $row->click_ip; ?>
</td>
