Programmatically remove a group from Microsoft Word Ribbon

I created a VSTO add-in for Microsoft Word Office 2010 and was looking for a way to programmatically remove a specific group from the feed when the add-in starts. At a later stage, users should be able to re-add this group using the Customize Ribbon feature in Word:

There is a function to switch the group’s visibility , but if I do this, try again to make the group visible using the Customize Ribbon feature:

groupName.Visible = false;

I searched a lot for this topic, but I can’t find anything useful regarding deleting tape groups, any advice would be great!
