  I think that's not exactly what I'm talking about.

  Look at this example.

  public class RegisterInput
  {
      [Required]
      public string FirstName { get; set; }
      
      [Required]
      public string LastName { get; set; }
  }
  

  Using that DTO with validation and provide this JSON to the app service:

  { firstName: "Emiliano", lastName: null }
  

  Then I will end up with an exception with a message like The field LastName is required

  I want to change that LastName to Last Name

  Is there any data attribute to set to the property to tell ABP to show Last Name as the display name for that property?

  try DisplayName

  [DisplayName("Last Name")]
  [Required]
  public string LastName { get; set; }

  Hi, most of the model validation attributes came from asp.net core. Abp only collect all the validations from those attributes and put the errors in AbpValidationException

  you can do something similar to this:

  [Required(ErrorMessage = "Last Name is required")]
  public string LastName {get;set;}
  

  Otherwise you can try using Abp Custom Validation instead

  The DisplayName Attribute could work, but how do I hook it up with the ABP Localization source? Does AbpDisplayNameAttribute work for this?

  Nope. AbpDisplayName is only used in Razor page.

  Use case:

  @Model.LabelFor(x => x.LastName)
