[MIM PAM] Adding groups and users from Portal with PRIVOnly Flag

When adding PAMusers and PAMGroups using powershell cmdlets, it's possible to set thePrivOnly Flag to mark the environment as PrivOnly, is this supported by the Portal as well ? 

For instance what would be the equivalent of this command using the admin portal : 
New-PAMGroup -SourceDomain contoso.corp -SourceGroupName T0-Admins  –PrivOnly
