How to remove sort in aggs in Kibana stacked bar chart

Elastic Stack Kibana
1

Hello, I have a really huge index with logs and I want to visualize some of them with a Bar Horizontal Stacked Kibana lens.
I add timestamp on Y-axis (1h interval), unique count of _id on X-axis, and i choose my url field as a break down by.

The problem is if I choose at least 4 hours, ES gives data too large memory error. When playing with raw query and profiling, I found the problem is in sorting in url bucket.
I tried to change it to Rank by -> Alphabetical and it goes not give error even for week, but shows only first urls sorted by name. Not an option for me.

The question is: how can I completely remove sort from agg query? ES itselfs shows only top N buckets sorted by number of documents. The aggs looks as follows:

  "aggs": {
    "0": {
      "terms": {
        "field": "ctxt_url.keyword",
        "size": 10,
          "order": {
             "2": "desc"
           }
      },
      "aggs": {
        "1": {
          "date_histogram": {
            "field": "@timestamp",
            "calendar_interval": "1h"
          },
          "aggs": {
            "2": {
              "cardinality": {
                "field": "_id"
              }
            }
          }
        },
        "2": {
          "cardinality": {
            "field": "_id"
          }
        }
      }
    }
  }
