Does Elasticsearch support transactional matters?

Elastic Stack Elasticsearch

Hi all,
is there any mechanism supported by elasticsearch for doing some operations in an Atomic way?

Example1:
Having two indices in place and you want to assign an alias per each (two different aliases) but in an Atomic manner (none or both).

Example 2:
Using _bulk endpoint but a force to all or none

Thanks in advance

No transactions in elasticsearch.
Alias endpoint operations are atomic though (per request).
