Hi @Sourav Kumar ,
it's not possible to sync user accounts from Microsoft Entra ID to an on-premises Active Directory.
I am not aware of any "connector" from Microsoft to get this sync from Entra ID to on-premises Active Directory done.
There might be a 3rd party solution available but I don't know. Another option might be to create a solution using PowerShell or similar.
