If you have a 1999-2000-2001 you're OK. If you have a 2002-2003 no CDL. If you have a 2004 you're OK. See the below photo. The round plate with the 3 bolts holding it down and center shift shaft. If I remember right it's on the passenger side of the car, you can reach under and feel it. (I'd do it when cold) If you ave one without the inside shifter (99-00-01). Again, if I remember right, you need a 10mm box wrench and you put it on the center nipple and shift it.
Grab yourself a telescopic mirror and place it above the front of your transfer case. If you see a threaded Nipple on a 3 bolt plate then you have it. If you see nothing but a flat blank spot then you don't.
IOWs grab a flashlight too, get on back underneath D2 and get a bit dirty looking.
Attached PDF top illustration show "nipple" and wrenching flats.

Technically if you have the CDL nipple then yes it was built in ready to go. BMW just decided not to attach a linkage until 04.
Most 99-02's will have the CDL Nipple. 02 models are a 50/50 chance as it depends on the build date. 03 never had the CDL Nipple.

If you have it you can grab an 03/04 SLABS Unit, and an 04 CDL linkage and call it a day.
You will have to either disable the 4wd interlock switch on the 99-02 transfer case or disable the one on the 04 linkage. Your choice on which one to disable. I prefer the 04 interlock as it's MUCH easier to get to in an event it fails out on the trail.
FYI, BMW sold out to Ford in 2000. Ford restored the working cdl for 2004 in response to customer requests.
Haha I thought about that afterward and felt it was too forward. What I meant was "you should search CDL and learn what you can about it."
Any Discovery owner that has no clue what CDL is should thoroughly inform himself. There is way too much to explain and it may be something that you will have an interest in. But it takes diagrams, footnotes, and days of back and forth correspondence found in threads for one to gain an understanding of what it is and what it does. Instead of "look for threaded attachment spigot at front output of transfer case," look the thing up in RAVE workshop manual and learn what it's function and value is. All you have to do is type "land rover CDL." It's not that hard and you get the benefit of knowledge rather than a string of bullet points.
All good man. After reading the write up, I just need to get off my butt and finish the driveshaft rebuild.

Ah interesting. If I understand you correctly, I could just use a 10mm closed wrench and put it in a diff locking mode? If so, is it clock or counter?

Yep whenever a company sells it takes a few years for the new owners ideas to start showing. The 04 CDL Linkage was truly a nice way for the D2 to go out in style.
You need to lock the diff in the middle to get to move.
Some Discovery 2's have a locking diff. Some do not.
Some have it but there is no way to lock it so you
need to crawl under and rotate a shaft to lock it.
