SCCM & Intune Co-management

Hi! I know that you know can manage bitlocker keys within Intunes on "Azure AD joined device". But is there any way to do the same with "Azure AD registred device"?

as seen on this https://msdnshared.blob.core.windows.net/media/2016/04/c.png) you aren't (See; Doamin joined + Device registration). But as I see it, it's just a easy string.

 

TL;DR: Do anyone know how to save a bitlocker key within Intune/Azure AD to those who are "Azure AD registred device" or "Hybrid joined"? Or do anyone know how to change a device from those mention above and make it "Azure AD joined device"?

Thanks for your time.
