[Question] How to prevent to compile Async and Decorator

[okian]

I'm using babel for transpiling like:
TSX -> ES6 -> Babel + webpack -> ES5
and I set noEmitHelpers to true in tsconfig.json, because babel handle it with single global helper instead of multiple helpers in each file but it doesn't work with Acyncs and Decorators and after compile i'm getting
__decorate(...)
and

__awaiter(this, void 0, Promise, function* () {
        ...
        });

How can I prevent tsc to compile Asyncs and Decorators and let babel handle them?

This is not yet possible, unfortunately. See #5361. Maybe add your voice over there to bump the issue.
