Is it possible to make rclone to use api key not oauth2? (gdrive)

Currently oauth2 is used for rclone to google drive,
but oauth2 does not restrictions,
api keys is better because it can be restricted to ip address
https://cloud.google.com/docs/authentication/api-keys#api_key_restrictions

so if someone stole my config file from vps he can not login since it restricted to vps ip.
Is it possible to make rclone use api keys instead of oauth2?
