Suppressing Outlook "This program is trying to access E-mail" pop-up for specific powershell script only

Question

When I run the following powershell script to send an e-mail :

$Outlook = New-Object -ComObject Outlook.Application
$file = Get-ChildItem -Path "H:\TP65655\IDX CVA\UAT" -Include *.idx -Recurse | Where {$_.CreationTime -gt (Get-Date).AddDays(-1)}
$atts = $file.fullname
$Mail = $Outlook.CreateItem(0)
$Mail.To = "email@domain.com"
$Mail.Subject = "Testing E-mail Automation"
$Mail.Body = "UAT TEST"
Try
{
    $Mail.Attachments.Add($atts)
    $Mail.Send()
    Write-Host "Mail Sent Successfully"
    Read-Host -Prompt “Press Enter to exit”
}
Catch
{
    Write-Host "File Not Attached Successfully, Please Try Again"
    Read-Host -Prompt “Press Enter to exit”
    Exit
}

The following pops up from Outlook :

Pop Up from Outlook

Is there any way I can remove this without changing the programmatic access in Trust Center to "Never" as this is an organization desktop and that option is not feasible.

@OwainEsau No. Changing the security settings is not feasible according to our organization policy — A coder, May 02 '22 at 09:55
Why are you using a COM object to send a mail instead of send-mailmessage? — bluuf, May 02 '22 at 10:08

You get a standard security prompt in Outlook. Your options are:

Use the Outlook Security Manager component which allows to disable such warnings at run-time dynamically.
Use a low-level API on which Outlook is based on - Extended MAPI. It doesn't throw security warnings or pop-ups. Or just consider using any wrapper around a low-level API such as Redemption.
Develop a COM add-in which has access to the trusted Application object. COM add-ins don't trigger such security prompts.
Deploy security settings via GPO.
Install any antivirus software with latest updates.
