Configuring 'Share Button' at Board Level

Hi there,

We've recently introduced the share button within our forum messages by using the XML explained here:

We can see that this has applied this share button to all our forum messages. I was wondering if there is any way we can control this to no appear at board level. We have a private board within our community that we would prefer not to have the share button included in.

Thanks.
