Populate a relation while filterting by specific attribute strapi

I have a single type that contains a relation with other collectionType. This collectionType has an attribute locale that is an enum with values fr-FR or de-DE.

I want to get the single type response populated, but in this population i want to show only the items that has locale fr-FR. Is it is possible using api rest?

I’m using this query but it returns all the results of the populated collection type:
/api/zero-query?populate=zero_query_populate_searches&filters[zero-query-populate-searches][locale][$eq]=fr-FR

Thanks a lot!!
