How can I change a dropdown selected option on page load? [duplicate]

I would like to change the selected option on page load using the class name.
Change selected option “– Select Option –” to “Curitiba”.

<select class="divi-acf et_pb_contact_select">
<option value="" selected="">-- Select Option --</option>
<option value="Almirante Tamandaré">Almirante Tamandaré</option>
