Update DomainDNSName,Netbiosname & Onpremisesamaccoutnanme without using AAD Connect

Hi,

We use okta for synchronizing accounts to Azure AD.

We plan to use AAD Join for our windows10 devices, it works well with AAD Connect(As AAD Connect synchronizes attributes DomainDNSName, NetBIOS name & Onpremisesamaccoutnanme)

Okta could not update these attributes, I want to find a way to update the attributes(by using PowerShell or GraphAPI?).

And also would like to know if there is any possibility to sync MSDS-Keycredentiallink attribute to on-premise without using AAD Connect so that I can use windows hello.
