So I found out about the `auto_expand_replicas` setting from [this thread](https://discuss.elastic.co/t/change-number-of-replicas-to-0-on-existing-indices/141622) while searching something else. I've set it to `false` and I will see if it works tomorrow when the new index is created.

EDIT: Marking this as the solution, since then the cluster configuration changed so I needed the replicas, as such I couldn't test it thoroughly, but this is as close of a solution I came, and I hope it can help someone.
