Yes, Its recommended to have antivirus on the Hyper-V host with proper exclusion.

Here is the exclusion list.

All folders containing VHD, VHDX, AVHD, AVHDX, VSV and ISO files

Default virtual machine configuration directory, if used  C:\ProgramData\Microsoft\Windows\Hyper-V

Default snapshot files directory, if used  %systemdrive%\ProgramData\Microsoft\Windows\Hyper-V\Snapshots

Custom virtual machine configuration directories, if applicable

Virtual machine virtual hard disk files directory. By default, it is C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks.

Custom virtual hard disk drive directories

Snapshot files directory. By default, it is %systemdrive%\ProgramData\Microsoft\Windows\Hyper-V\Snapshots.

Vmms.exe (Note: May need to be configured as process exclusions within the antivirus software)

Vmwp.exe (Note: May need to be configured as process exclusions within the antivirus software)

Additionally, when you use Cluster Shared Volumes, exclude the CSV path C:\ClusterStorage and all its sub-directories.

Hope that helps.

Cheers !
