I do not have DMS in my ADD in or COM add in.  

Where do you see the DMS tab? I don't have one.

It's on the toolbar in Lacerte.  We no longer subscribe to DMS and I want the icon grayed out or disabled.  

My response assumed you referring to the DMS add in for Excel and Word.
There are many icons in the toolbar that I don't use and have manage to mentally grey out. Good Luck.
