TooManyFieldsSent Raised when saving admin.ModelAdmin with TabularInline even with unchanged fields

Whenever I try to save without editing any fields in Author in the admin page, I get a TooManyFields error. I am aware that I can simply set this in settings.py.

DATA_UPLOAD_MAX_NUMBER_FIELDS = None 
# or DATA_UPLOAD_MAX_NUMBER_FIELDS = some_large_number 

However, not setting a limit would open up an attack vector and would pose security risks. I'd like to avoid this approach as much as possible.

My admin model AuthorAdmin has a TabularInline called PostInline.

admin.py

    class AuthorAdmin(admin.ModelAdmin)
        inlines = [PostInline]

    class PostInline(admin.TabularInline)
        model = Post

Models

    class Author(models.Model):
        name = models.CharField(max_length=100)
        
        def __str__(self): 
            return str(self.name)

    class Post(models.Model):
        title = models.CharField(max_length=100)
        author = models.ForeignKey(Author, on_delete=models.CASCADE)

        def __str__(self):
            return str(self.title)
     

The reason this error is being raised is that an Author can have multiple posts. Whenever this Author is saved (without any field change), it sends out a POST request which includes the post_id and the post__series_id based on the number of posts under that same author. This can easily exceed the default limit set by Django which is set to 1000.

Is there a way to not include unchanged fields in the POST request upon save? Or a better approach to solve this issue without having to resort to updating DATA_UPLOAD_MAX_NUMBER_FIELDS?

class PostInline(admin.TabularInline)
    model = Post

    def has_change_permission(self, request, obj=None):
        return False
