Graph APIs Support for On-premise Exchange server
Are there any ways to use Graph APIs to talk to an on prem Exchange? I know that they can talk to a cloud only or hybrid setup but is it also possible to be able to use this for an on prem only kind ...

There is no way to use Graph API for pure on-prem (Exchange). Theoretically, I think it will be cost-effective to have hybrid with one dummy user on the cloud and then use Graph API to access all other users data from on-prem via cloud. I have not done it and I am not sure if there is any hidden cost beside one user (which is $5 per month - https://www.microsoft.com/en-us/microsoft-365/business/compare-all-microsoft-365-business-products). If someone know if it is possible to setup hybrid with only one user and it does really cost $5 per month, then this is the best option as it does not cost on-prem customer much and it saves mataining two code (EWS for Exchange and Graph for cloud users).
