The 2000-2006 2500 suburbans still had 8 lugs. They kept the 2500 suburban/Yukon XL going to the 2013 model year(and it still had 8 lugs). There weren't any manual transmissions offered in the 2000+. After 2000, the only engines were the 6.0 and the 8.1. the only engine offered after 07 was the 6.0.
There is a 3500 suburban offered 2016 to present(and its 8 lug), but they are all goverment orders.
I dont think it made much sense to have a diesel suburban to begin with( at least with underpowered diesels). In the GMT400 platform, the diesel had 420 ft/lbs of torque. The 454 had 410. Is that 10 ft/lbs worth the extra maintainence and cost and noise?

Nicely done.
One of the motivations for the diesel Suburban (in my mind, anyway) was fuel economy.
The 454 would get 8-10 mpg with the engine shut off coasting down a hill. I had a squarebody 2wd diesel Suburban that was probably in the high 20's for fuel use. When equipped with the 40 gallon tank you couldn't time your bathroom breaks with your fuel stops because your bladder would explode first.
