Everyone has said the same thing.
If you change your DCC suspension to coil overs without the DCC, you will simply lose the ability to change the dampener setting.
Steering, engine, throttle, diff, air con and ACC if you have it will be unaffected. The DCC delete is just to stop you getting error messages and make it easier to swap back.
If you're not bothered about having comfort mode etc in suspension only, then you’re fine.
Or if you’re like
@theoldboy and want to keep comfort for when you’re cruising, then get the KW or Bilstein coilover lots that can plug into the DCC and work like the standard setup. But it’s just more £££
