in Template display_Forums_item
find

<td class="posts-count"><vb:if condition="!$isSubcategory">{vb:number {vb:raw forum.posts}}</vb:if></td>

replace with

<td class="posts-count"><vb:if condition="!$isSubcategory"><vb:if condition="!in_array($forum['nodeid'],array(1,2,3))">{vb:number {vb:raw forum.posts}}</vb:if></vb:if></td>

where (1,2,3) are the node id's of the forums you want to hide post count

you can do the same thing with topics count in the same template

<td class="topics-count"><vb:if condition="!$isSubcategory">{vb:number {vb:raw forum.topics}}</vb:if></td>

you can do the same thing in template display_Topics_item if you want to disable post counts in topic list .
