You could make the strings not visible by using the Visible? property node.
Otherwise you could move the front panel on the vi so that the boolean array is the only visible indicator (you have to scroll down to see the strings) and then save the vi. This should only make the boolean array visible when you call it in the subpanel, but the user can still scroll down to the strings with the scollbars on the subpanel. So if you do not want the user to see the strings at all, it is better to use the visible property node.
