Data Action Timeout on Large Payloads in Multi-Org Deploy

Is it possible to extend the execution timeout for custom Data Actions within Genesys Cloud Architect flows? Our AppFoundry integration processes bulk updates across multiple organizations, but requests exceeding 10,000 records consistently trigger a 504 Gateway Timeout using Node.js SDK v4.2.1. The payload validates correctly against the v2 schema, yet the connection drops before completion. Are there specific configuration limits for platform API integrations that we might be missing?
