Can I load a serverless file using some yaml library?

I am trying to load a serverless file using a yaml library to do some preprocessing:

const yaml = require('js-yaml');
const file = await fs.readFile(path, { encoding: 'utf8' });
const doc = yaml.load(file);

I am getting an error:

YAMLException: unknown tag !<!Ref> (26:42)

Because of this line:

S3_BUCKET: !Ref ComposerBucket

Is it possible to load serverless files into an object somehow? I'm thinking maybe serverless is using some particular schema that I need to define when loading, but I don't know.

const doc = yaml.load(file, { schema: 'serverless-framework' });

Do you have any idea how I can get this to work?

I found the solution while browsing the serverless npm package source code:

const cloudformationSchema = require('@serverless/utils/cloudformation-schema');
const doc = yaml.load(file, { schema: cloudformationSchema });
