I spoke with my Chevy dealer today who said they use Mobil1 ESP.
Here they say Castrol EDGE 0W40 is dexos 2 approved (?) https://msdspds.castrol.com/bpglis/FusionPDS.nsf/Files/29D862369255C1598025838300446319/$File/BPXE-B8NBC4.pdf

So you are pretty much stuck with Mobil 1 ESP if you wish to follow the Dexos 2 recommendation.
