Is it possible to downgrade Windows Server 2016 Datacenter to Standard?

DISM /online /Get-CurrentEdition to know the version and after;

DISM /online /Get-TargetEditions to know what it can be switched to, and after try

DISM /online /Set-Edition:<Version> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEULA
