Upload files to SharePoint Online as System Account - powershell

Question

How do I upload files and create folders to SharePoint Online through PowerShell while keeping their metadata (Modified By) as "System Account" instead of having the files using my account on the metadata?
I know I can change the metadata for files by doing this:
$user = Get-PnPUser -ErrorAction Stop | ? Email -eq $email
$newFile["Author"] = $user.id
$newFile["Editor"] = $user.id
$newFile["Modified"] = $currentFile.LastWriteTimeUtc
$newFile["Created"] = $currentFile.CreationTimeUtc
$newFile.Update()
But how about folders? If I use CSOM with PowerShell (see below) I can't find a way to modify the metadata properties for "Author" and "Editor":
$CSOM_credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($cred.UserName, $cred.Password)
$CSOM_context = New-Object Microsoft.SharePoint.Client.ClientContext("https://tenanturl.sharepoint.com")
$CSOM_context.Credentials = $CSOM_credentials
$ParentFolder = $CSOM_context.web.GetFolderByServerRelativeUrl("Samples")
$newFolder = $ParentFolder.Folders.Add("New Folder")
$ParentFolder.Context.ExecuteQuery()
$CSOM_context.Load($newFolder)
$CSOM_context.ExecuteQuery()
If I use the PnP PowerShell (Add-PnPFolder), I have the same problem I can't get a way to modify the same metadata

You can use "SHAREPOINT\System" to set Author and Editor to System Account.
$Id = 1024
$item = Get-PnPListItem -List "listNmae" -Id $Id
Set-PnPListItem -List "listNmae" -Identity $Id -Values #{"Author" = "SHAREPOINT\System";
"Editor" = "SHAREPOINT\System";
"Modified" = $item.FieldValues.Modified
}
Also you can get System Account user using
$sysaccount = Get-PnPUser | ? {$_.LoginName -eq "SHAREPOINT\System"}
