How to suppress decorator

[Sczlog]

I use tsoa to create a restful server, and want to speedup test with sucrase but found sucrase is not support decorator now and not transform it, so jest run failed.
Decorators in tsoa mostly are only identifier and has no logical code, I would like to suppress all decorator in code, is there any way to do this?

Perhap I can write another jest transformer run before sucrase
