creating bigquery views take too much space in the google deployment manager yaml, resulting that our deployment-manager.yaml file exceeds 1MB

Problem:
creating bigquery views take too much space in the google deployment manager yaml, resulting that our deployment-manager.yaml file exceeds 1MB:
https://cloud.google.com/deployment-manager/quotas
Question:
Is there a way to insert sql files into the string field in the deployment manager from a bucket or git repository?

view:
type: object
description: The view definition.
properties:
query:
type: string
description: |
The query that BigQuery executes when the view is referenced.

Or any other ideas to use the deployment manager for a lot of views with long sql statements?
We currently are exploring these options:
1: adapt the deployment manager yaml to use sql files
2: take out the bigquery views from the deployment manager and create custom CI/CD build scripts
