I can’t do the partial method as I’ve already ordered.

Okay, then It's the DNA.

Might do DNA and say the driver posted a note through my door saying it was around the side of my house

Do the drivers for the carrier In question actually leave packages at the premises, or do they (only) strictly request a signature on delivery?

They require a signature I don’t believe they leave it outside but that doesn’t mean to say it hasn’t happened before and that it won’t happen when they deliver mine

I see your point, and It could work (or fail) depending on a very Important factor as follows.

If they have a 100% record of obtaining a signature on delivery, then It will well and truly work against your claim- more than likely fail.
