Hello!
Even though it's not possible to change the UV Set ID as if it were a property on the Texture Coordinates node, you may use one or more toggle switches to alternate between Texture Coordinate nodes with different ID's or, as an alternative, use one Lerp node instead of the toggle.

Please let me know if this helps you out, thanks!
