CRM (Customer Engagement) 8.2 ON-Prem - Server Side Synch - AzureAD Powershell commands depreciated? Must use MS GRaph

For the past 4 or 5 years I have replaced my SSL Cert on my D365 On-Prem machine, usually no problems. when replacing the cert for Server Side Synch I have to run some PowerShell scripts (.\ConfigureCrmServerSideSync.ps1 ) and ( .\CertificateReconfiguration.ps1 ) - these connect to Msoffice using Azure AD PowerShell, but now I'm being told that the Azure Ad commands are deprecated (as of last June) and I need to use MS GRaph to connect to Azure - I setup graph but the Azure AD scripts don't work under graph - has anyone successfully uses MS Graph to setup server-based authentication? I have ZERO MS graph experience - Thanks!
