Toggle background polling on/off ?

[brianbyrnebg]

Hi,
I'd like to disable / enable health check polling via a feature flag.
I was thinking I could adapt this:
Is there a way to change HealthChecks.UI.Configuration.SetEvaluationTimeInSeconds dynamically at runtime?
and set EvaluationTimeInSeconds to -1 so that the Task.Delay in HealthCheckReportCollector.cs would delay infinitely, which would disable polling. However I don't think this is the correct approach because once the the task is delayed infinitely I don't see how polling could be ever started again.

Is there a away to achieve toggling the background polling on/off?

Thanks for any help.
