sharepoint online – Add AD Security group as Site collection administrator – SPO

Is there a way to add a security group as Primary or secondary site collection administrator to all the sites in the tenant via PowerShell?

I know this works for adding a user account to all the sites as SC Admin

$Sites = Get-SPOSite -Limit ALL
Foreach ($Site in $Sites)
Set-SPOUser -site $Site.Url -LoginName $AdminName -IsSiteCollectionAdmin $True

The same command with Set-SPOSiteGroup does not work

Set-SPOSiteGroup : A parameter cannot be found that matches parameter name 'IsSiteCollectionAdmin'

Since ‘IsSiteCollectionAdmin’ is not accepted with Set-SPOSiteGroup

Any suggestions on how to set security group as site collection administrator via PS script/ cmdlets?
