Kibana Instance Crashing During PDF/CSV Export on Elastic Cloud

Hi,

I am experiencing frequent instance crashes when attempting to export default dashboards (PDF/PNG/CSV) from Kibana. I am currently using Elastic Cloud and do not have access to the underlying terminal or the physical kibana.yml file to adjust server settings.

Example of Report causing the crash:

This results in the instance crashing with 502 bad gateway error message from Nginx.

I would like to implement best practices to stabilize these exports. Specifically, I am looking for the correct way to apply the following via the Elastic Cloud Console's "User settings overrides":
Reporting Timeouts: Increasing xpack.reporting.queue.timeout to allow more time for complex dashboard rendering.
Memory Allocation: Since I cannot set NODE_OPTIONS via terminal, what is the recommended way to ensure Kibana has enough RAM for heavy X-Pack reporting tasks on Cloud?
CSV Size Limits: Safely adjusting xpack.reporting.csv.maxSizeBytes without destabilizing the node.
PDF Size Limits: xpack.reporting.queue.timeout, xpack.reporting.kibanaServer.hostname and xpack.reporting.thumbnails.enabled: false
Could you provide an example of the YAML snippet I should paste into the Kibana user settings section of my deployment to fix this?

Environment:
Deployment: Elastic Cloud (Hosted)
Version: kibana 9.3.0
