Removing tags from a data store
You can remove one or more tags associated with a data store. Removing a tag does not delete the tag from other AWS resources that are associated with that tag.
At the terminal or command line, run the untag-resource command, specifying the Amazon Resource Name (ARN) of the data store where you want to remove tags and the tag key of the tag you want to remove.
aws healthlake untag-resource --resource-arn "arn:aws:healthlake:us-east-1:674914422125:datastore/fhir/b91723d65c6fdeb1d26543a49d2ed1fa" --tag-keys '["key1"]' --region us-east-1
If successful, this command does not return a response. To verify the tags associated with the data store, run the list-tags-for-resource command.
