@RobinDeFal The effect is the same, the difference is that the filters panel is available to the end user, and they can modify and remove those filters. This method effectively removes the capability of an end user to see or modify anything.
Create two of the same slicers, making sure one of them (referred to as 'first slicer') only has 'interactions' with the other slicer ('second slicer') and nothing else on the page. Select the chosen items from the first slicer and it will filter the second slicer to only show those options available. Go to View->Selection Pane and hide the first slicer so it is no longer visible and you're sorted.
