It looks like the 3 is comes with a standard quick release, but does it come with or can I order the axle drop-outs to run a 142x12 axle?

No problem to do it, but you'll need to order the dropouts AND axle from Giant.
The Giant dropouts have a proprietary thread pitch and only Giant axle will work (even though it's a DT Swiss made axle)

There's a chance that the 3 might be shipped with the dropouts. Ask your LBS what came in the box.

My 3 did not come with any dropouts. LBS quoted me $13 for the 142x12 dropouts, but couldn't find the axle in the system (so take that price with a grain of salt).

$13 sounds about right for the dropouts. Axle should be about $50

Not sure why it's not showing up in the system. Have your LBS ask their Giant rep for part #.
Another option that's worked well for me is to message Giant directly on Facebook. They usually respond to questions within a few hours.

Good luck with the conversion.

can someone explain how this works as my Anthem 3 only has 1 replaceable dropout?

Thanks

it's on the inside of the dropout
