Put a eventListener in your select, disable the irrelevant inputs and hide them. You can save information to help you search the attribute data of HTML

$('#TipoDocumento').change(function(e) {
  let opcaoSelecionada = this.querySelector('option:checked');
  
  //desabilita e esconde todos os inputs
  let inputs = $('#InputsDocumento input');
  inputs.attr('type', 'hidden');
  inputs.attr('disabled', '');
  
  //habilita e mostra o input relevante
  let inputEscolhido = inputs.filter('#'+ opcaoSelecionada.dataset.tipo);
  inputEscolhido.attr('type', 'text');
  if (opcaoSelecionada.dataset.tipo !== 'placeholder')
     inputEscolhido.removeAttr('disabled');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script><selectid="TipoDocumento" name="TipoDocumento" class="form-control">
  <option data-tipo="placeholder">Selecione o tipo de documento</option>
  <option data-tipo="RG">RG</option>
  <option data-tipo="CPF">CPF</option>
</select>

<span id="InputsDocumento">
  <input type="text" id="placeholder" placeholder="Documento" disabled>

  <input type="hidden" name="RGPessoaAutorizada[]" id="RG" placeholder="RG da pessoa autorizada" disabled>

  <input type="hidden" name="CPF[]" id="CPF" placeholder="CPF" disabled> 
</span>
