I am considering doing that. I also considered replacing the wireless card though I was unable to find reliable information if the BIOS has some kind of whitelist that would prevent me from doing that.
Lenovo definitely has blocklists for its laptop upgrades (otherwise I’d have repurposed the empty WWAN slot on my X1 Nano for a second SSD), but I’ve not heard of Dell doing the same. At the very least my old 2008 Dell laptop has no hint of anything like that.
