Setting up and managing device configurations using Intune
anonymous user, From your description, it seems we use Microsoft Intune to deploy a security baseline policy. And some devices get the status "Not applicable". If there's any misunderstanding, feel free to let us know.
For the status of "Not applicable", the status represents a device that can’t receive the policy. Like the one you said the hardware is not support. If so, we need to remove the setting which cause the hardware not supported from this policy to make the policy applied. Or we can deploy a new security baseline policy without this affected setting to these affected device to make it work. To find the affected setting, we can check the per-setting status under monitor. Here is a link with more details for the reference:
