Entity EF6 opposite of include

Say the EF6 code first is used. Say we have a simple two table relationship. Where a patient has one doctor associated.

class Patient
{ 
   [Key]
   public int id { get; set; }
   public string Name { get; set; }
   [ForeignKey("Doctor")]
   public int DoctorId { get; set; }
   public virtual MedicalPersonel Doctor { get; set; }
}
class MedicalPersonel 
{ 
   [Key]
   public int id { get; set; }
   public string Name { get; set; }
}

There is a function Include(string path) to load the Doctor, when I am loading the patient. But what would be the opposite of include if I don't want to load the Doctor if the doctor contains some big fields like images?

Thanks!
