Move COD Vanguard, Black Ops Cold War, MW 2019 to Steam?

Is there any chance we can get our purchases moved to Steam and if we purchased the games on, can we be granted a Steam version of the games now that Microsoft is in the process of acquiring Activsion-Blizzard? I see that MW2 2022 will be on Steam and I would rather not have 2 apps. If I can get rid of and not have it running continuously in the background it would be great.
