Using Powershell To Filter Data Types In CSV

Hi, I am working on a script to generate CSV after filtering out columns of certain Data Types.
In particular, I am wondering how I would specify an Identity type column comprised of:

column (Data Type: INT, Property: (Identity Increment=1 and Identity Seed=1))

My code is below at the bottom (and the actual filter items are in the next to last line - just below).

Exclude-ColumnsByType -ExcludeType System.String, System.DateTime

Thanks for any help.

# !! Define the function to process each pipeline input object and,
# !! for efficiency, use a steppable pipeline to invoke Select-Object
function Exclude-ColumnsByType {
  param(
      [Parameter(Mandatory, ValueFromPipeline)]
      $InputObject,
      [Parameter(Mandatory)]
      [string[]] $ExcludeType
  )
  begin { 
    $propertiesToInclude = $null
  }
  process {
    if (-not $propertiesToInclude) {
      $propertiesToInclude = $InputObject.psobject.Properties.Where({ $ExcludeType -notcontains $_.TypeNameOfValue }).Name
      $steppablePipeline = { Select-Object -Property $propertiesToInclude }.GetSteppablePipeline()
      $steppablePipeline.Begin($true)
    }
    $steppablePipeline.Process($InputObject)
  }
  end {
    $steppablePipeline.End()
  }
}

$MyConnection = Connect-DbaInstance -SqlInstance LOCALHOST\MSSQLSERVER -TrustServerCertificate

#Define a list of tables
$Tables = @('aaaa1_table4', 'aaaa1_table5', 'newspic', 'news')

#Iterate through the list
foreach ($Table in $Tables) {
  #Build the query
  $Query = "SELECT * FROM $Table;"

  #Build the output file path and remove the schema, dot, and v from the file name
  #and append the .csv extension
  $CsvPath = "C:\CSVOut\b\$Table.csv"
  
  # !! Exclude-ColumnsByType is now called in the pipeline to operate on the 
  # !! Invoke-DbaQuery output objects.
  #Run the query and export results to CSV
