yes you need just to create service account for databricks and than assign storage admin role to bucket. After that you can mount GCS standard way:

1. bucket_name = "<bucket-name>"
2. mount_name = "<mount-name>"
3. dbutils.fs.mount("gs://%s" % bucket_name, "/mnt/%s" % mount_name)
4. display(dbutils.fs.ls("/mnt/%s" % mount_name))

here link for ur refer before process, hope some info help on this case
