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