you will need to combine RDP property configuration and GPO settings.
In Azure Virtual Desktop, the redirectclipboard:i:value RDP property controls clipboard redirection. Setting this to 1 enables clipboard redirection, while 0 disables it. You can customize RDP properties for your host pool either through the Azure portal or using PowerShell with the -CustomRdpProperty parameter in the Update-AzWvdHostPool cmdlet.

After setting the clipboard redirection in AVD, you can use Group Policy to allow or disallow clipboard redirection for specific users or groups.
