Windows 10: Windows MDS mitigation gone after update to 1909?

I just updated my Laptop (I5 4200U) from version 1903 to 1909. Before updating, the SpeculationControl Powershell script showed:

Windows OS support for MDS mitigation is present: True
Hardware is vulnerable to MDS: True
Windows OS support for MDS mitigation is enabled: True

After the update, this changed to:

Windows OS support for MDS mitigation is present: True
Hardware is vulnerable to MDS: True
Windows OS support for MDS mitigation is enabled: False

I couldn't find anything regarding this issue; is there a way to re-enable MDS mitigation?

How to Enable MDS Mitigation?

I just updated my laptop to v1903 and installed KB4497165: Intel microcode updates. The security report looks fine apart from the extract below:

Speculation control settings for MDS [microarchitectural data sampling]
Windows OS support for MDS mitigation is present: True
Hardware is vulnerable to MDS: True
Windows OS support for MDS mitigation is enabled: False

Should I enable Windows OS support for MDS mitigation and how do I enable it?

 

How to Enable MDS Mitigation?

Have the same issue on my Windows 10 PC. Have tried to with adding new registry values, but didn't help. Perhaps MDS mitigation is not yet implemented for versions 1903 and 1809?
