There are no standards that apply here.

Remarks

You can use this method to dynamically modify the state of Thumbnail Toolbar buttons. Because all buttons must be added before the Thumbnail Toolbar is displayed, this method gives you control over which buttons are visible or active. Temporarily hide buttons that are not currently needed by setting fVisible to VARIANT_FALSE. You can also configure the buttons to be visible but not active by setting the fEnabled flag to VARIANT_FALSE.

Alternatively, you can replace the button entirely with IShellUIHelper4::msSiteModeAddButtonStyle and IShellUIHelper4::msSiteModeShowButtonStyle.
