@Sumit Kumar Jha Currently devices on the Windows Server platform don’t support mobile device management (MDM) and can’t enroll in Microsoft Intune. With the Microsoft Defender for Endpoint (MDE) Security Management feature, Windows Servers can receive security management policies from Intune.

So, ASR and Defender Policy are supported by Windows Servers.
For ASR, please refer to the following article:

It is needed to have Windows 10 Enterprise E5 or E3 License. Although attack surface reduction rules don't require a Windows E5 license, with a Windows E5 license, you get advanced management capabilities including monitoring, analytics, and workflows available in Defender for Endpoint, as well as reporting and configuration capabilities in the Microsoft Defender XDR portal. These advanced capabilities aren't available with an E3 license, but you can still use Event Viewer to review attack surface reduction rule events. So, choosing an E5 or E3 license depends on whether you need advanced management capabilities.
