Global setting for AsNoTracking()?

Since this question is not tagged with a specific EF version, I wanted to mention that in EF Core the behavior can be configured at the context level.

You can also change the default tracking behavior at the context
instance level:

using (var context = new BloggingContext())
{
    context.ChangeTracker.QueryTrackingBehavior = QueryTrackingBehavior.NoTracking;

    var blogs = context.Blogs.ToList();
}
