How to upload a 9.6GB sql.gz file to SQL

I have been advised earlier on this platform that to upload my sql.gz file to BigQuery, I have to upload the .gz file to a bucket in Cloud Storage, and use the bq command-line tool to create a new table. It seems to me that, in order to do this, I have to activate Cloud Shell, and my question now is: how much storage space will I have then? On a YouTube tutorial - https://www.youtube.com/watch?v=RdDyF3jVbbE - it is mentioned that Cloud Shell only gives 5GB of storage, however, my file is 9.6GB. What are my options?
