Selected Case, If Case 0 = then Combobox3 Enable = False

Good day,
Trying to figure our how to do the following:

Userform:

Private Sub ComboBox2_Change()
ComboBox3.Clear
    Select Case ComboBox2.ListIndex
        Case 1
            arrData = list1
        Case 2
            arrData = list2
        Case 3
            arrData = list3
        Case Else
            Exit Sub
    End Select
    ComboBox3.List = arrData
End Sub

My list is based on a control sheet that I have but I need that if Combobox 2 = Case 0 then to make my Combobox3.Enable = False and if not Case 0 then Combobox3.Enable = True.

Is this possible or I would need a (Combobox2_Change) If / Else /End If function?
