Can I delete monitoring and logging indexes?

As I mentioned in my previous post (AppSearch disk consumption keeps growing), my EES+ES node is quickly filling up the disk, even my document count and size is pretty stable

Kibana shows me that my most heavy indexes are
.monitoring-es-7-2020-XX-XX : 700MB each.
.ent-search-api-ecs-logs-togo_production-7.6.0-2020-XX-XX: also 700MB each
.ent-search-app-search-analytics-ecs-logs-togo_production-7.6.0-2020-XX-XX: 200MB each

I don't use any of the analytics features in appsearch.
Can I delete or make some operation in order to reduce their size?
In my last post my HD was 12GB, now it's 50GB!
