I'm just brainstorming here:
Would it be possible to delay the order of monday untill thursday? I'm not sure if it MUST be a non-intentional delay. You can't write a note to the driver he must come back or it will fail the DNA. You need to be unavailable untill thursday. If you then can SE him to leave both packages at your doorstep, that's 2 for the price of 1 DNA. But you can't make the driver sus.

But I don't know what DHL does when you're not at home and how often they come to your house again. Maybe someone with experience can give advice?
