increase per_page limit in rest api

We need to increase the per_page limit on responses to a rest api request.
afaik – the limit is 100

There used to be a way to filter that param, but it seems this filter hook is no longer working: rest_post_collection_params

Is there any way to increase that limit? Without hacking the codebase?

We understand the repercussions of increasing the limit, but we need to exceed the per_page in a single call for use in code that will not be distributed.
