I was able to modify /includes/locations/class-acf-location-post-template.php with a workaround. I’ll post the whole file here for clarity. I added a class method acf_location_post_template::acf_get_post_templates() then changed both calls to the native get_post_templates()

<?php 

if( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

if( ! class_exists('acf_location_post_template') ) :

	function initialize() {
		// vars

		$this->label = __("Post Template",'acf');
