Invoke command, powershell, ssh, don't log the output

Hello,

We have a powershell script, that returns some data which we need to complete the workflow. That's good, but that script will retrieve a Password from the vault. But when the script does his work, we can see the password, so by using the script from VRO, the script runs, and we see the password in the Log of that Workflow.

Is there a way to prevent any log made into the workflow ? Or skip a part of the log ? But we need to keep receiving the password, I just don't want any output to display in the vco gui.

Thanks!
