Hi @anfield,

Yes — this is possible using IRE Identification Rules + Data Source Rules for SCCM specifically.

     using only:

• Serial Number
• SMBIOS_GUID

and qualify it for SCCM source.

Do NOT heavily customize the OOTB Hardware Rule directly.

Instead:

1. Create a new Identification Rule
2. Set higher priority than OOTB rule
3. Add condition:

Discovery source = SCCM

1. Use identifiers:

• serial_number
• smbios_guid

Ensure:

• SCCM always populates SMBIOS_GUID consistently
• serial numbers are normalized
• IRE precedence order is validated

source-aware identification through identification rules and reconciliation definitions

• using stable unique identifiers
• minimizing OOTB customization
• using source-specific reconciliation behavior where possible

This is the safest long-term approach for SCCM-specific identification behavior.
