Hacking the climb portal option?

Hi, how do you override the climb portal option? Can’t find an option in Zwift hacks. Is there a tag to add in the prefs. file?

I’ve tried playing around with the preferences file but it seems to update on launch every time and despite removing permission i still didn’t get it working.

I don’t really use the climb portal so not bothered to chase up the easiest way is probably to change your system time.
