Here is the working demo that I think will fit in your case.

$(".modal").on("shown.bs.modal", function () {
    if ($(".modal-backdrop").length > 1) {
        $(".modal-backdrop").not(':first').remove();
    }
})

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

 <div class="container">

        <!-- Trigger the modal with a button -->
        <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>

        <!-- Modal -->
        <div class="modal fade" id="myModal" role="dialog">
            <div class="modal-dialog">

                <!-- Modal content-->
                <div class="modal-content">
                    <div class="modal-body">
                        <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal2">Open Modal</button>
                    </div>
                </div>
            </div>
        </div>
        <!-- Modal -->
        <div class="modal fade" id="myModal2" role="dialog">
            <div class="modal-dialog">

                <!-- Modal content-->
                <div class="modal-content">
                    <div class="modal-body">
                        <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal3">Open Modal 3</button>
                    </div>
                </div>
            </div>

// Make sure only one backdrop is rendered 
 $(document).on('show.bs.modal', '.modal', function () {
        if ($(".modal-backdrop").length > 1) {
            $(".modal-backdrop").not(':first').remove();
        }
    });
    // Remove all backdrop on close
    $(document).on('hide.bs.modal', '.modal', function () {
        if ($(".modal-backdrop").length > 1) {
            $(".modal-backdrop").remove();
        }
    });

$(document).on('show.bs.modal', '.modal', function () {
    if ($(".modal-backdrop").length > -1) {
        $(".modal-backdrop").not(':first').remove();
    }
});

Let CSS handle it.

.modal-backdrop:nth-child(2n-1) {
  opacity : 0;
}

You can add/remove data-backdrop="false" attribute depends on requirement. Else you can also include css like

.modal-backdrop+.modal-backdrop {
  opacity : 0;
}
