How to modify properties using serilog enrichers?

logging

I need to modify specific property value (compress stacktrace property of exception) of object logged using serilog.

public class CustomEnricher : ILogEventEnricher
    {
        public void Enrich(LogEvent logEvent, ILogEventPropertyFactory propertyFactory)
        {
            var errorContainer = logEvent.Properties["errorDetails"];
        }
    }

In the above code, i m getting the log message in errorContainer (LogEventPropertyValue type).

But not able to access the particular property which i want to modify.

Basically im logging the exception and want to compress stackTrace property of exception before logging.

Can a property be modified using Enricher ?

Is there any alternate solution for this ?

What I have tried:

I tried looking at existing enrichers but nowhere found enricher that is modifying existing value.
