Find OneDrive Provisioned Users missing from ADgroup

There is a way to look up users who have a provisioned with the Get-SPOSite -IncludePersonalSite parameter.

But I'm trying to find a way to see which of my users do not already have a PersonalSite provisioned to prep for our OneDrive Deployment. Would like to use a specific AD Group and see if they have a PS site already created.

I'm obviously missing something since the below code returns all users, not the users that don't have a Personal site.

$SPOMembers = (Get-SPOSite -IncludePersonalSite $true -Template "SPSPERS#10" -Limit All).Owner
foreach ($item in $SPOMembers)
{
  Get-ADGroupMember myADgroup -Recursive | ForEach-Object {get-aduser $_.SamAccountName} | 
  Where-Object { $_.UserPrincipalName -ne $item } 
}
