Try this in forumhome_forumbit_level2_post:

Find this or something similar to:

		<if condition="$show['subforums']"><div class="smallfont" style="margin-top:$stylevar[cellpadding]px"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>

And replace it with:

<if condition="in_array($forumid, array(x))">
<else />
		<if condition="$show['subforums']"><div class="smallfont" style="margin-top:$stylevar[cellpadding]px"><strong>$vbphrase[subforums]</strong>: $forum[subforums]</div></if>
</if>

Change the "x" to the forumid you want the sub-forums hidden. To add more parent forums just add ", y, z".

Remember to enable show sub-forums in Admin CP.
