Can't disable ASP.NET Core `Activity` due to missing `None` log level

[OwnageIsMagic]

https://github.com/dotnet/aspnetcore/blob/913ff28b8e834b51ded284118accebdaf85697a9/src/Hosting/Hosting/src/Internal/HostingApplicationDiagnostics.cs#L105

_logger.IsEnabled(LogLevel.Critical); condition is always true when using Serilog.

Previous issue about None closed with filter workaround, but it's not applicable here.

[OwnageIsMagic]

There is LevelAlias.Off, but it's not recognized in configuration.

Any luck using its numeric equivalent, 6?

[OwnageIsMagic]

Yes, anything greater than 5 works, thanks.
So issue can be moved to serilog/serilog-settings-configuration
I think the simplest solution will be to add explicit check for "Off" here

serilog-settings-configuration/src/Serilog.Settings.Configuration/Settings/Configuration/ConfigurationReader.cs
