How to increase List View threshold in PowerShell - powershell

Question

I have a very large SharePoint folder with many nested subfolder and I'm trying to count how many items are in there before we migrate that folder to different location.
I've this simple script but I'm always getting this error when every I tried to count a folder that really large so just wondering how can I increase the threshold or fix this issue.
$SiteURL = "https://company-my.sharepoint.com/personal/hello_nam_corp_com"
$searchfor = "/Documents/Archive"
$folderpath = "Documents/Archive"
$CSVFile = "C:\Users\Desktop\Resource\FolderStats.csv"
#Connect to SharePoint Online
Connect-PnPOnline $SiteURL -useWebLogin
#Get the list
#$documents = Get-PnPList -Identity $ListName | Where-Object {$_.Title -eq 'Documents'}
$FolderItems = Get-PnpListItem -List $folderpath
$fieldvalues = $FolderItems.Fieldvalues
$result = #()
foreach ($field in $fieldvalues) {
$obj = New-object psobject -property $field
$result += $obj.fileref
}
$final = $result | where-object {$_ -match $searchfor}
$item = New-Object psobject -Property #{
FolderName = Split-Path -Path $searchfor -Leaf
URL = $searchfor
filesfoldercount = $final.count
}
$item
$item | Export-Csv -Path $CSVFile -NoTypeInformation
Get-PnpListItem : The attempted operation is prohibited because it exceeds the list view threshold.

Try below PowerShell.
#Parameters

#Connect to SharePoint Online
Connect-PnPOnline $SiteURL -Interactive
#Get the list
$List = Get-PnPList -Identity $ListName
#Get Folders from the Library - with progress bar
$global:counter = 0
$FolderItems = Get-PnPListItem -List $ListName -PageSize 500 -Fields FileLeafRef -ScriptBlock { Param($items) $global:counter += $items.Count; Write-Progress -PercentComplete `
($global:Counter / ($List.ItemCount) * 100) -Activity "Getting Items from List:" -Status "Processing Items $global:Counter to $($List.ItemCount)";} | Where {$_.FileSystemObjectType -eq "Folder"}
Write-Progress -Activity "Completed Retrieving Folders from List $ListName" -Completed
$FolderStats = #()
#Get Files and Subfolders count on each folder in the library
ForEach($FolderItem in $FolderItems)
{
#Get Files and Folders of the Folder
Get-PnPProperty -ClientObject $FolderItem.Folder -Property Files, Folders | Out-Null
#Collect data
$Data = [PSCustomObject][ordered]#{
FolderName = $FolderItem.FieldValues.FileLeafRef
URL = $FolderItem.FieldValues.FileRef
FilesCount = $FolderItem.Folder.Files.Count
SubFolderCount = $FolderItem.Folder.Folders.Count
