Answer 1

If I understand your question, you want to script an ActiveX not marked as safe. You can't. This is exactly the purpose of this setting, to block execution of scripts not explicitly allowed by the user.

As a solution, you could run a powershell script in the client machine to mark the desired ActiveX as safe.
