Is there any way to change cluster_cookie in already bootstrapped cluster?
Should I just set new cartridge.cfg.cluster_cookie and reboot Tarantool instances or some additional actions are required?

Setting a new cookie and restarting every instance is enough. You can set it either in cartridge.cfg() options, or in instance.yml config. Don't forget to update it everywhere, or the Cartridge will complain that a member is non-decryptable.
