ABP Framework version: 6.0.2
UI Type: Angular
Database System: EF Core (SQL Server)
Tiered (for MVC) or Auth Server Separated (for Angular): yes
Exception message and full stack trace: Guid generated using EntityHelper.TrySetId does not match the standard for GUID
Steps to reproduce the issue: Create an entity and wait for id generation

I would like to know:

1: how to replace or override a function over EntityHelper or any other static helper. EntityHelper.TrySetId is causing a lot of problems on my system, the GUIDs do not match the standard for GUIDs [a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[1-5][a-fA-F0-9]{3}-[89abAB][a-fA-F0-9]{3}-[afA-F0-9]{12}

2: if it is possible to stop the Id generation setting as default configuration on module setup

3: One example of how to use DisableIdGenerationAttribute

You can replace the IGuidGenerator service.

For example:

[Dependency(ReplaceServices = true)]
[ExposeServices(typeof(IGuidGenerator))]
public class MyGuidGenerator : IGuidGenerator, ITransientDependency
{
    public virtual Guid Create()
    {
        return Guid.NewGuid();
    }
}

You need to use the DisableIdGenerationAttribute

For example:

public class MyEntity : AggregateRoot<Guid>
{
    [DisableIdGeneration]
    public override Guid Id { get; protected set; }
}
