Windows Exploit Protection: what is SEHOP setting: “TelemetryOnly” for?

I’m reading myself into the different exploit protection methods from MS. One is SEHOP, if I check it e.g. with PS:

Get-ProcessMitigation -System

I get:

    Enable                             : NOTSET     TelemetryOnly                      : OFF     Audit                              : NOTSET     Override SEHOP                     : False 

What is "TelemetryOnly" ? Internet search was not successful so fare.

Thanks for hints and resources!
