ElastifcSearch UpdateByQueryRequest from 6.2 to 7.4.2

Question

I have to upgrade our ES from 6.2 (TCP client) to 7.4.2 (REST API)

And I have a little problem with UpdateByQueryRequestBuilder, that looks like need to be change to UpdateByQueryRequest (doc). The old code looks like this:

BoolQueryBuilder dateQueryBuilder = ...
QueryBuilder a = ...
BoolQueryBuilder b = ...

UpdateByQueryRequestBuilder updateByQuery = new UpdateByQueryRequestBuilder(tcpClient, UpdateByQueryAction.INSTANCE);
updateByQuery.filter(dateQueryBuilder.filter(a).filter(b)).script(updateScript);

As I wrote, I'm understanding UpdateByQueryRequestBuilder (that using the oldest client) should be replace with UpdateByQueryRequest but this new API haven't filter method (just setQuery that will replace the current query in chain case...)

UpdateByQueryRequest updateRequest = new UpdateByQueryRequest();
updateRequest.setQuery(dateQueryBuilder)
    // .setQuery(a) - will replace dateQueryBuilder instead of chain new filter...
    // .filter - not exist in the new API

So the question, how should I replace this code with newest ES REST API (or chain the queries)?
