TCM Mod for GM 10 Speed

[sealandsky]

Has anyone heard of a modified TCM for the GM 10 speed transmission? I'm driving a 2019 Yukon Denali and while the 10 speed up-shifts crisply and other wise works well - It's always trying to achieve about 1,500 RPM. I'd like to modify the shift points if possible, or find something "canned" that is more slanted towards a performance profile.
