Server 2016/Server 2019 Mixed Mode Domain

Hello Experts,
We are upgrading our hybrid domain to server 2016 level in order to utilize Azure AD.
Can we have server 2016 domain controllers and server 2019 member servers and still be considered a 'native mode' domain?
Also, can we have server 2016 domain controllers and have server 2012 member servers and still utilize Azure AD?

Thanks in advance for your insight!

I get the strong suspicion that you are mixing terms without strong definitions.  What do you Eman by a "hybrid" domain?  Unless you still have NT4 in the mix... Which would be blocking 2016 DCs.

At any rate, you can AADConnect doesn't care about member servers.  DCs only matter if you plan on using Windows Hello for Business.   Everything else is agnostic within the supported OS versions.
