Deployment and licensing in an air gapped environment

Hi there,

We're considering Microsoft Defender for Endpoint for an industrial site with about 120 Linux hosts. None of the hosts are allowed to connect to the Internet, ever.

We can only use USB drives to upload changes to the hosts.

1. Installation of Microsoft Defender for Endpoint is not an issue, we can just deploy the packages and install.

2. We found recent documentation that suggests we can maintain and refresh virus definitions in an offline network too: https://learn.microsoft.com/en-us/defender-endpoint/linux-support-offline-security-intelligence-update

3. The only question we are left with is: if we purchase licenses, can we 'redeploy' them to that site without any Internet access? So, I think the short question is "we want to onboard an offline host?"

Thanks!
