Add paddle shifters to a 2018+ Giulia?

I picked up a 2018 Giullia Q4 Lusso over the summer and am loving it so far. It's got every option I want except for paddle shifters. I talked to two Alfa dealers in my area (Northern CA) to see if they'd install them for me. But they both said that they are not able to do that. Has anybody had success with getting paddle shifters added by a dealer? One dealer said he might be able to do it if I'd give him the part numbers, but I can't find them online. He said that it doesn't come as an installable kit for my car.

I may have to try to order the parts on ebay and do it myself, but am hesitant to try this on a 2018+ since the ODB port is locked down and I'd have to pull some small wires and figure out how to reflash the ECU. I'll probably end up breaking something.

Here she is at the Concorso Italiano in Monterey parked next to a Stelvio.
