You can also run an additional m.2 ssd in the WWAN slot which works just fine assuming you grab the correct type. It's not the standard m.2 though. It's weird and has 2 notches instead of 1. My understanding is when it comes to this slot only specific drives will work properly. I grabbed an SN520 512gb (2242 size by the way, the standard 2282 is too big and 2232 is too small) off of ebay and I'm booting from it as we speak. https://www.westerndigital.com/products/internal-drives/pc-s...
So when it comes to the standard m.2 slot my understanding is that there are no limitations, but the using the WWAN slot as an ssd slot can lead to issues unless you get the correct one.
Unfortunately I don't have any insight about running freebsd on this machine, so good luck to you there.
