Can one leave the DPF on and just run a programmer than shuts off the DPF?

No. With the DPF on and no regen process taking place to clean it out, it will just clog up full of particulate matter.

Absolutely not. The tuner will get rid of regeneration mode and the DPF will fill up and cause a bunch of issues. No good.
