That would be desirable, but is not really practical in FileMaker.
You could put the button object inside an invisible tab controll and use script trigger scripts to select an empty tab. That would keep the hand from appearing as the button would be hidden inside the tab control.
To make a tab control invisible, you give it fill and border colors that are either transparent or that match the color of the layout background.
To use a script to select a tab and bring it to the front, use the Inspector to give each tab an object name and use Go To Object.
Now that 13 is out, yes you can.
Use the "Hide object when" feature - have two button duplicates in the same spot where one is active and one isn't, and then use the hide feature to toggle them upon a certain condition.
