No, there's no specific setting to disable it. You can either edit it out of the template or have a plugin made to disable it. Going the plugin way will keep your templates unedited and any future updates to it will automatically apply, which is what I usually suggest.
If you want to edit the template thought just find this code in "forums > front > forums > topicRow" (line ~113):
<a href='{$row->url( "getPrefComment" )}' class='' title='{{if $row->mapped('title')}}{$row->mapped('title')}{{else}}{lang="content_deleted"}{{endif}} {{if $row->canEdit()}}{lang="click_hold_edit"}{{endif}}' {{if $row->tableHoverUrl and $row->canView()}} data-ipsHover data-ipsHover-target='{$row->url()->setQueryString('preview', 1)}' data-ipsHover-timeout='1.5'{{endif}}{{if $row->canEdit()}} data-role="editableTitle"{{endif}}>
and replace it with (basically remove the data-ipsHover attributes):
<a href='{$row->url( "getPrefComment" )}' class='' title='{{if $row->mapped('title')}}{$row->mapped('title')}{{else}}{lang="content_deleted"}{{endif}} {{if $row->canEdit()}}{lang="click_hold_edit"}{{endif}}' {{if $row->canEdit()}} data-role="editableTitle"{{endif}}>
