How to deploye azure client without user input? In ninjaOne

I am trying to deploy the Azure VPN Client across multiple endpoints using NinjaOne.

The provided PowerShell installation script requires user interaction (confirmation prompt), which prevents it from being executed silently through an RMM tool. Additionally, we are not using Intune, so the deployment must be done entirely through scripts or other non-Intune methods.

Could you please advise on:

How to install Azure VPN Client in silent mode (no user interaction) using scripts?

Whether there is an official unattended installation method (PowerShell, MSI, or other deployable package) suitable for bulk deployment?
