Stop folder recurse when - powershell

Question

I'm trying to do the following -
$OutFile = "C:\temp\Audit_Permissions.csv"
$Header = "Folder Path,IdentityReference,AccessControlType,IsInherited,InheritanceFlags,PropagationFlags"
Del $OutFile
Add-Content -Value $Header -Path $OutFile
$RootPath = "\\netapp\DATA"
$Folders = dir $RootPath -recurse | where {$_.psiscontainer -eq $true}
foreach ($Folder in $Folders){
$ACLs = get-acl $Folder.fullname | ForEach-Object { $_.Access }
Foreach ($ACL in $ACLs){
$OutInfo = $Folder.Fullname + "," + $ACL.IdentityReference + "," + $ACL.AccessControlType + "," + $ACL.IsInherited + "," + $ACL.InheritanceFlags + "," + $ACL.PropagationFlags
Add-Content -Value $OutInfo -Path $OutFile
}}
The problem is that about 3 or 4 levels deep into the folder structure I no longer need to do a recursive. There's the potential for thousands of folders in the format of yyyy\mm\dd which I want to ignore. yyyy being the first folder.
so I want the audit on something like this -
\\netapp\data\folder1
\\netapp\data\folder2
\\netapp\data\folder2\folderA
\\netapp\data\folder3
\\netapp\data\folder3\folderA
\\netapp\data\folder3\folderA\testfolder
But as soon as it hits the following in any tree I want it to stop going further down -
\\netapp\data\folder3\folderA\testfolder\yyyy

This is one way to omit the foldername with yyyy.
You can adjust the RegEx part if you want to be more precise.
$Folders = dir $RootPath -recurse | where {($_.psiscontainer -eq $true) -AND ($_.FullName -notmatch '\\\d{4}($|\\)'}
