disabling the system button in vive hand controller

[pitbool]

Hi,

We are running a study with the vizard running the vive. The user is frequently pressing the system button on the controller (the one right below the trackpad) and the menu pops up, which we want to avoid.

We checked vizard help for standard commands to disable that button, but no luck. Any pointers?

Thanks in advance!
