Adding a 2nd drive to a Dell notebook

[IamMe18]

Hello
I have a quick question. I have a Dell Latitude E5470 and I was wondering if it'll be possible to add a 2nd storage drive in an empty WWAN slot.

I've read success stories from people using different models from Dell but haven't found a definite answer on my particular model.

Dunno but there's another method https://www.instructables.com/Add-a-Second-SSD-to-a-Dell-Latitude-E5470-Laptop/
