Stop whining around, man.
You wanted a cheapo lens, you got one. +5 AFMA on the D500 - are you joking to complain about that peanut? I had lenses which needed around +15, one was +25. So what? Do it and get sharp pics afterwards. Why are you trying so desperately to ignore the fact there are tolerances - and there are as well, at least in your D500, inbuilt routines to compensate them?
You can try to send the lens to Sigma to adjust it. Matter of fact, I don't know which Nikon serves as reference to their own calibration, but it can't be a good one - I always have to adjust the lens, no matter if Nikon or Sigma (or Tamron). The 100-400 was a pure exception in my eyes.
