How to disable template engine?

Im using jackc/tern/migrations and in one of .sql files I do insert with using {{}} to insert parameters later. But (If I understood correctly) due to template engine in this lib sql is ignoring esc characters and that parameters whether being seen like sql functions (which doen't exist) or just saying that I have 'unexpected { in command. What should I do and how can I disable template engine?

No file, test, or entry point is named. Start by tracing tern's migration SQL parsing and template configuration to determine how literal {{}} is handled; done means establishing and documenting or implementing a supported way to disable templating without breaking SQL parameters.
