XF 1.4 Hide Members Tab

That theme will require specific changes. But for the most part you want to use a conditional to show the tab on the pages that use it and no others.

You can wrap the member tab code in this, i did it like this except in a template modification. It is to show the code contained within ONLY if it matches these controllers that use it:
Code:
<xen:if is="{$controllerName} == 'XenForo_ControllerPublic_Member' OR {$controllerName} == 'XenForo_ControllerPublic_Online' OR {$controllerName} == 'XenForo_ControllerPublic_RecentActivity'">


</xen:if>
 
It's not a setting. You can put the board into debug mode and make a template modification.

This is what I have for the stock/stock like theme code. You would need to adjust the find to match the template for UI.X and if your literally copy pasting the member code tab which may change in the future, may also require future updates to the template mod:
