Search for Kess/Ktag. The alientech version is a few grand, the chinese knock-offs are a couple hundred. (Same as Tech 2's used to be Bosch vs knock-off) You need to verify that it'll read/write your ecu & you'll need to be careful you don't change parameters that'll damage the engine. If you eliminate regen, you'll need to fab a straight pipe to replace the dpf (or punch out the existing dpf) or you create too much back pressure.
It will be an illegal mod, subjecting you to epa fines if reported, and it will void warranty if you care about that & will reduce your resale value. Doubt any shop will do it, since potential fines aren't worth what they can charge you. If you know any hot rodders/racers/sled pullers, they can help you find the areas to modify in the programming. You may end up needing to do ALL your own repair work if epa mandates reporting of modded systems by licensed shops.
If it was me, & i was to choose to do this, I would keep the dpf and a copy of the original program somewhere safe, so i could put back to stock if/when i sold or needed to have the tractor worked on by someone that might report me.
All things considered, keeping as is until you find a used pre-emissions tractor you like that you can buy, then sell the newer tractor to fund repairs/refurb is probably a better option.
