Filter Log By Event Id (or by LogMessage)

In nLog I am able to setup (in nlog.config or via Code) some so called ConditionBasedFilters like:

<filters defaultAction='Log'>
        <when condition="equals('${event-context:item=EventId}','Microsoft.EntityFrameworkCore.Model.Validation.DecimalTypeKeyWarning')" action="Ignore" />
</filters>

With this I can filter log messages based on the actual LogMessage or EventId etc. (see Official nLog doku: https://github.com/NLog/NLog/wiki/Filtering-log-messages#example-in-c )

Is there some similar feature in asp.net core Logging? (see: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/logging/?view=aspnetcore-5.0#how-filtering-rules-are-applied )

As far as I can see it only supports filtering on LogLevel, Category and Provider but not on for instance the actual LogMessage or EventId - Is there some feature, that I am missing?

This filter works for me:

<when condition="equals('${event-properties:item=EventId}',99150001)" action="Ignore" />
