Alternate stylus for Boox Max Carta

I have been using the Boox Max Carta for about a week, and it has been working great for me. The only annoying thing that I have run into is that when taking notes on it, I keep accidentally pressing the button on the side of the stylus (probably caused by me not holding pens correctly). I was wondering if there was an option to disable that button, or purchase a different stylus that would work on this device that does not have a button on it.
