Intune policy + Linux machines

I recently added my Ubuntu 24 LTS machine to Intune and applied a compliance policy — it worked well without any issues. After that, I created an antivirus policy and an EDR policy under the Endpoint Security section. However, the policy is not being assigned to the system. I’ve tried all assignment methods, including using a user group, device group, and the “All devices” option, but none of them worked.
