 > If you have previously whitelisted the kernel extension as part of your remote deployment, that warning should not be presented to the end user.

To proactively silence the warning, you can still deploy a configuration to whitelist the kernel extension. Refer to the instructions in the [JAMF-based deployment](mac-install-with-jamf.md#approved-kernel-extension) and [Microsoft Intune-based deployment](mac-install-with-intune.md#create-system-configuration-profiles) topics.
