Hi!
Sorry for the delay!
The Wazuh report can not be edited, you can use Kibana Visualize and Kibana Dashboards to create your custom reports.
I leave you here some tutorials, to see the options and usage of these tools. OpenDistro/OpenSearch Kibana and ElasticStack Kibana have some differences, but is a good way to start customize your own reports.
You can use as reference the Dashboards you like from the WazuhApp.
Let me know if that helps.
Regards.
