Windows 11 24H2 In Place Upgrade - Compatible CPUs issue

Question

Hi everyone, we're planning the upgrade from Windows 10 to Windows 11 24H2 version. Months ago, we made the readiness collections on Configuration Manager (Ready and Not Compliant) using the official Microsoft Query found on documentation. We're now facing some issues when we try to update some clients that are marked "Ready" using IPU task. Even if the CPU **(**Intel(R) Xeon(R) Gold 6336Y CPU @ 2.40GHz ) is in the compatible list here Windows processor requirements Windows 11, version 24H2 supported Intel processors | Microsoft Learn, when we launch the IPU task, it fails when checking the compatibility prerequisites. Checking the logs, we noticed that it failed on "CpuFMS" value:

2025-06-10 11:35:22, Info                  CONX   hwreqchk: TRACE,Windows::Compat::HardwareRequirements::Evaluate::PreProcessRules,345,*** Adding rule property='CpuFmsBlockingIntel' & value='True (1)' to inventory list ***

Verifying the summary check, all variables result is set to "NoIssue" except for CpuFMS

2025-06-10 11:35:22, Info                         CHWReqChecker: checked CpuFms, found HardBlock.

We executed a systeminfo on this client and the family of the cpu is Model 45 and it seems to be NOT allowed according to what the In Place Upgrade checks. How is it possibile? Is there some kind of extra verification that we can do so we can understand if the CPU is really compatible? Has the SCCM query for readiness been changed recently? if yes, can I have the upgraded version for 24H2? Thanks.
