Hi,
You can manage Cumulative Update for .NET Framework via WUFB
The Cumulative Update for .NET Framework Classifications remain the same as for the Cumulative Update for Windows and continue to show under the same Windows Products. Updates that deliver new Security content will carry the “Security Updates” classification and updates carrying solely new quality updates will carry either the “Updates” or “Critical Updates” classification, depending on their criticality.
Reference: Types of updates managed by Windows Update for Business
