You are running version 7.17, this setting only exists from version 8.6.

For version 7.17 you need to follow this [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/fix-common-cluster-issues.html#_error_disk_usage_exceeded_flood_stage_watermark_index_has_read_only_allow_delete_block).

Try to increase the size of watermark, if this does not solve you will need to keep delete indices until there is enough free space.
