Add validations to AddressValidator

Hello,

I need to add more validations to the addresses, I don't want to change the original code.
Is there a way to do this with a plugin?

I tried to implement this but only the rules that are translated to the client side work.

If I try to create a custom validation, the validation is ignored.

        public class AddressValidator : BaseNopValidator<AddressModel>
    {
        public AddressValidator(ILocalizationService localizationService,
          IStateProvinceService stateProvinceService,
          AddressSettings addressSettings,
          CustomerSettings customerSettings)
        {
      
      //This Works
            RuleFor(model => model.Address2)
            .NotEmpty()
            .WithMessage("Error");

      //This Works
            RuleFor(model => model.Address2).MinimumLength(2)
            .WithMessage("Error");

      //This does not work
            RuleFor(model => model.Address2).Custom((x, context) =>
            {
                if (x == "Test")
                {
                    context.AddFailure("Error");
                }
            });
    }
  }
