Problem with query for XLS

I was using the old version of the metabase and I was able to set the Timeout in the "default.clj" file within "metabase/query_processor". However, in the current version the file no longer exists, and that's why my large queries break when exporting XLS.
When the file existed I changed the line "config/is-prod? (u/minutes->ms". Where can I change the timeout now that the file no longer exists?

You shouldn’t modify the code, rather use a reverse proxy and modify the timeout there
