The official wwan card can be found on ebay , example
Dell Precision 7540 7740 Laptops DW5821e 4G WWAN Card HMGJ3 | 1 Year Warranty | eBay
same goes for the interposer. lot from china, one from slovakiahttps://www.ebay.de/itm/178131820701
the caddy is also abundant from china ( even in combination with the interposer ) on ebay ( and from china only, as far as I can anyway see )
and the batteryhttps://www.ebay.co.uk/itm/305426940848

This is a 2019 system, so Dell likely won't have the parts. Try parts-people.com or EBay.
The WWAN card is a standard part, and you should verify support with whatever OS you're running and with your service provider.
