The trigger name format can be customised in two ways, either globally for every trigger, or for a specific entity.

Global trigger name format

1. Use the UseTriggerNameFactory() option on your DbContextOptions:

   services.AddDbContext<MyDbContext>(options =>
   {
    options
        .UseSqlServerChangeTriggers(options =>
        {
            options.UseTriggerNameFactory(tableName => $"{tableName}_CustomTriggerName")
        });
   }
   

For a specific entity

1. In your model builder configuration, use the ConfigureChangeTrigger() extension method to set a trigger name format for a specific entity:

   protected override void OnModelCreating(ModelBuilder modelBuilder)
   {
    modelBuilder.Entity<User>(u =>
    {
        u.ConfigureChangeTrigger(options =>
            {
                options.TriggerNameFactory = tableName => $"{tableName}_CustomUserChangesTrigger";
            });
    });
   }
