I know the dealer won't...that's a safety device and no dealer would disable that.
However, if you search on the Deere Owning/Operating forum, you'll find several guys who did disable that switch. I don't have a 3032 (I wouldn't buy a tractor without off seat PTO capability, but that's no criticism of you!!), so those guys might be better to help you.
Try using "3032 PTO operation" as a search query...focus on the Deere Owning/Operating and the general Owning/Operating forums.
As far as "I were to get it from the actual company making the
chipper, how do I go about doing that?"...just compared other brands (visually) with the frontier unit. I'm pretty sure it's Salsco or Wallenstein. Then, go to their websites and do a dealer search.
There is a downside, if you have a Quick Hitch. The Frontier is probably set up for a Quick Hitch...the OEM unit may not be.
