ICMP Timestamp Response vulnerability Solution

I am trying to see if anyone is facing similar issues.
Despite Setting the DWORD value on HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters >> DisableIcmpTimestamp value to 1, IVM still reports the machine as vulnerable.

It is happening on a selected number of Windows 10 devices running 1903 build.
Anyone facing similar issues or is there a different remediation so that IVM can set this case to rest?

What is IVM reporting as the proof of the finding? Also I want to make sure there is an agent on this machine and/or has been rescanned since the remediation.

I have also seen settings like these get overridden by GPO as well so double check to verify that the setting is still present.
