Unable to apply data patch: elasticsearch6

Unable to apply data patch MagentoCatalogSearchSetupPatchDataSetInitialSearchWeightForAttributes for module Magento_CatalogSearch. Original exception message: Indexer handler is not available: elasticsearch6

What is the best way to get either around this or fix this?

Note: I cannot get into my admin, I cannot run the setup: upgrade command as the message above halts the upgrade process. I have access to the config files and the database.

Version: Magento EE 2.3.3
