Here is some clarification from Stellantis:
Valvoline Premium Blue Extreme 5W40 is an option that satisfies all requirements:

M1 TDT is likely to be a bit more robust. There have been some stellar results with this oil.
if it isn't under warranty any CK4 rated 5w40 is going to do the job for the 2017 specs, simply because the modern CK4 oils supercede the CJ4 oils still specced in 2017... ... now if you are bound and determined to find an oil that meet's Mopar's more esoteric specifications , get the Rotella stuff online.
Any diesel 5w40 will be fine if it meets the required standards 
Gen2 requires a diesel oil, not Euro Gas Engine Oil.
I would use a MS-12991 spec or A3/B4 spec 5W-40. It'll be superior to CK-4 for not much difference in price.

Most here know that I'm not a fan of certifications and the indirect ceilings they put on oil performance. Oils like High Performance Lubricants CK-4 HDMO 5W-40, Amsoil Signature HDMO 5W-40, and Driven DR40 5W-40 would be among the ones I'd be looking at if insisting on sticking with a CK-4 add pack.
Sure, this isn't per the manual. Quite frankly though, if we all simply just followed the manual, why would we be here?
I received an excellent report earlier this week from a 2017 Gen2 using High Performance Lubricants No VII Euro 10W-40.

Mobil Delvac currently has their rebate ongoing. I’d pick Mobil Delvac ESP 5w40.

Ford list above is a good start. Pick whatever 5w40 within the above list.
QSUD Euro 5w40 is a dual-rated oil. It carries several diesel spec approvals including VW's 505.00 and FCA's current EcoDiesel spec MS-12991.
QSUD Euro does not meet CJ4/CK4 requirements, which is what the Gen2 Ecodiesel now requires.
Technically, it requires a synthetic low-ash oil that meets the Chrysler specification MS-10902, and is also CJ4 certified.
I did not claim QSUD meets CJ4 spec, just corrected the statement that it is only a "Euro gas engine oil," and added that it meets several diesel specs, including the current EcoDiesel specs for the latest gen engine.
OP: you can find online options as well, see here.
Not sure if you read this, but the language is a little funky:
I am not aware of the MS-10902 spec being low ash; I don't see how Rotella 5W40 fits the definition of a low-ash oil.
The Gen2 and Gen3 requirements are completely different.
I did, and thanks for including (might be helpful for others).
Perhaps as far as "heavy-duty diesel" engine oils go, anything below 1% SA is considered low ash?
Indeed, big difference between Gen2 and Gen3, as the latest engine has been "redesigned to be 70+% all new," or so they say. Along with this latest gen, the oil spec was changed as well. I think more concerning is that FCA will not be offering it beyond 2023 models.
The oils that meet this latest spec also carry several Euro approvals, like Porsche A40 and MB229.5 so I wouldn't consider these oils as "not up to the task" for a light-duty passenger diesel engine like the EcoD.
