Gorm 请问设置了关联后,数据库可以不添加外键的吗

代码

package model

import "gorm.io/gorm"

type Note struct {
    gorm.Model
    UserId   int
    GroupId  int
    Question string `gorm:"size:256"`
    Answers  []NoteAnswer
}

type NoteAnswer struct {
    gorm.Model
    NoteId  int
    Content string `gorm:"size:256"`
}

db.AutoMigrate(&model.Note{})
db.AutoMigrate(&model.NoteAnswer{})

这样子创建数据表后会在NoteAnswer 里面增加外键和索引，可以怎么限制不创建关键和索引的吗，

The document you expected this should be explained
