may help you . I need to select only 3 options from the multiple select. If user selects more than 3 options than the last selected element should be replaced by the new one clicked.
code :
var lastOpt;
$('#testbox option').click(function () {
    lastOpt = $(this).index();
});
$('#testbox').change(function () {
    if ($('option:selected', this).length > 3) {
        $(' option:eq(' + lastOpt + ')', this).removeAttr('selected');
    }
});

I hope this helps you . When looping all the options, if the option is not the selected one, you need to re-enable it.
code :
const $selects = $(".products-combo");
$selects.on('change', function(evt) {
    // create empty array to store the selected values
    const selectedValue = [];
    // get all selected options and filter them to get only options with value attr (to skip the default options). After that push the values to the array.
    $selects.find(':selected').filter(function(idx, el) {
        return $(el).attr('value');
    }).each(function(idx, el) {
        selectedValue.push($(el).attr('value'));
    });
    // loop all the options
    $selects.find('option').each(function(idx, option) { 
        // if the array contains the current option value otherwise we re-enable it.
        if (selectedValue.indexOf($(option).attr('value')) > -1) {
            // if the current option is the selected option, we skip it otherwise we disable it.
            if ($(option).is(':checked')) {
                return;
            } else {
                $(this).attr('disabled', true);
            }
        } else {
            $(this).attr('disabled', false);
        }
    });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="products-combo" name="product[]">
  <option>Select 1</option>
  <option value="1">Product 1</option>

With these it helps Based on our discussion in the comments, we can do it this way (not tested):
code :
  before_action :adjust_ransack_params, only: [:show]

  private

  def adjust_ransack_params
    # Only change it if the status_eq is failed
    if params.dig(:q, :status_eq) == 'failed'
      params[:q].delete(:status_eq)
      params[:q][:status_in] = %w(failed partial)
    end
  end
