Application.Ribbon.Tabs.Clear

Remove method of the Tab object deletes it from the Ribbon.
Remove all Tabs, except specific one:
Dim nIndex As Integer
Dim oTab As Object

For nIndex = Application.Ribbon.Tabs.Count To 1 Step -1

Set oTab = Application.Ribbon.Tabs(nIndex)
If oTab.Name <> TAB_PRINT Then
oTab.Remove
End If
