On the 6.7l yeah, but I doubt it on the 6.2l.
Sounds like the dealers are still ordering those crappy 3.73s for all the gasser lot trucks. Some things never change. The 3.73s shouldn't even be offered in a CC.
Here is the Ford statement out of their book. The transmission is the same in both the 6.2L Gas and the 6.7L PSD.

Torque converter provides connected feel and better efficiency
The torque converter of the 6R140 transmission is designed to be accurately controlled and efficient. A closed-piston design provides precise control of the lock-up clutch. Its torque multiplication is matched with the rest of the powertrain for better off-the-line performance, but that’s only the start. Once under way, a long-travel, high-capacity turbine damper allows the torque converter to dampen out the extreme torsional force produced in particular by the new, more powerful diesel engine.
“
This damper allows us to lug down to 900 rpm while our competitors lug to around 1,100 rpm,” Bruck said. “This technology allows us to stay locked more, which means the engine can run at a lower rpm and get better fuel economy.”

I'm not sure if they can electronically change it. Both truck have the same transmission version.
