What do you mean "pretty much useless"? It's pretty useful to me.
I'm pretty sure it's possible, you need to unpack data and then edit the relevant part.
It's also possible to disable DRS on a per-track basis, by making DRS zones nonexistent. If you do that then be sure to backup the original file.
Or you could simply let DRS be and just not use it. AI drivers will use it, but that shouldn't be a big issue since according to you it's pretty much useless?
