Those 3 are part of default chain. So if you stop using schemaless one, you get them anyway.
https://solr.apache.org/guide/solr/latest/configuration-guide/update-request-processors.html#default-update-request-processor-chain If you define a different custom chain, I think you need to add them manually though. Also, when you disable schemaless, make sure you don't have implicit conversions happening that the chain also provides. E. G. Date as text gets converted to real date. If you do, you may want to remove just schema generation part or create a custom chain with only bits you need.
