How to filter products on the product detail page?

Question

1C-Bitrix

Hello connoisseurs!
On the detailed product page , using the API, I display products selected by certain properties. Everything is fine, everything is displayed. But since the result_modifier is loaded before the template, the GET request cannot be sent to it and, accordingly, the $arFilter array cannot be changed! The question is, how can these products be filtered, for example, through a GET request? So that you can filter these products by the link for example /catalog/platy/pechatnaya-plata-big-size-1366/?destination=small-size . Share good advice!

As an option, process the request in the detail.php file in which the bitrix.catalog.detail component is called and pass the necessary parameters to this component
