How to adjust the size of a generic Modal Bootstrap window according to the desired View

Question

I have a generic bootstrap modal window that will open several views. The problem is that each of them will have a different screen size and currently, my settings remain fixed(style="width: 800px; height: 500px;")... Is there any way I can change both parts of the code to meet this requirement?

(Generic Modal where all Views are open)

<div class="modal fade modal-primary" id="modalGenerica" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="static">
    <div class="modal-dialog modal-dialog-centered" style="width: 800px; height: 500px;">
        <div class="modal-content">
            <div id="contentModal"></div>
        </div>
    </div>
</div>

(Example of a view with parts of the Modal structure)

@model Retaguarda.Application.ViewModels.CustomerViewModel
@{
    ViewData["Title"] = "Register new Customer";
    Layout = null;
}
<div>
    <form asp-action="Create">
        @Html.AntiForgeryToken()
        
            <div class="modal-shadow">
                <div class="modal-header modal-header-primary">
                    <button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
                    <h4 class="modal-title text-center"> @ViewData["Title"] </h4>
                </div>
                <div class="form-horizontal">
                    <vc:summary />
                    <div class="panel-body">
                        <div class="form-group">

You can use a modal with view-based responsive dimensions (see comments in CSS). Example:

.modal-content{
   height: 60%; /*altura da modal*/
}

.modal-dialog{
   max-width: 50%; /*largura da modal*/
   height: 100%; /*altura da view da modal (não alterar)*/
   margin: 0 auto !important; /*centralizar modal horizontalmente*/
}

#contentModal{
    overflow: auto; /*habilita o overflow no corpo da modal*/
}

#modalGenerica{
   overflow: hidden; /*evitar overflow da view da modal*/
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css">

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#modalGenerica">
  Abrir modal
</button>

<!-- Modal -->
<div class="modal fade modal-primary" id="modalGenerica" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true" data-backdrop="static">
    <div class="modal-dialog modal-dialog-centered">
        <div class="modal-content">
            <div id="contentModal">
               Conteúdo da modal
            </div>
        </div>
    </div>
</div>
