I’m trying to learn .NET8 and I’m building my first API. In my project I’m using Identity.EntityFrameworkCore to be able to handle user related stuff.
I created my custom User class in order to add a few properties for the user, here is my class.

using Microsoft.AspNetCore.Identity;
using System.ComponentModel.DataAnnotations;

namespace Blog.Models.Entities
{
    public class User : IdentityUser
    {
        [DataType(DataType.DateTime)]
        public DateTime? BirthDate { get; set; }
        public string? FirstName { get; set; }
        public string? LastName { get; set; }
        public byte[]? ProfilePicture { get; set; }
        public virtual ICollection<Article>? blogs { get; set; }
    }
}

I did the required configuration and I got access to the default endpoints /login, /register… which is perfect, but when I try to register a user, I can only provide the email and passowrd in my request body but I want to be able to provide the other properties I created in my custom User class and to do that I created my custom register endpoint

[HttpPost("register")]
public async Task<IActionResult> Register(RegisterUserDto input)
{
    var user = new User()
    {
        FirstName = input.FirstName,
        LastName = input.LastName,
        BirthDate = input.BirthDate,
        Email = input.Email,
        UserName = input.UserName,
    };
    var result = await _userManager.CreateAsync(user, input.PasswordHash);
    string message = string.Empty;
    if (result.Succeeded) 
        return Ok("User created successfully");
    return BadRequest("Error occured");
}

And I got the expected result. However my problem is that now, I do have 2 register endpoints, the one provided by Identity and the one I created. I can remove

builder.Services.AddIdentityCore<User>()
    .AddEntityFrameworkStores<AppDbContext>()
    .AddApiEndpoints();

and

app.MapIdentityApi<User>();

from Program.cs,
but that will also get rid of the other endpoints such as /login, /refresh, /forgotPassword… which I want to keep.
And so my question is, is it possible to only get rid of the default register method while keeping the others?
