Encrypting source URL (and filters)

I have a valid Thumbor URL that works: https://thumbor.arvutitark.ee/xIPGHvXZ8VkGc8JPgCW0SqQ_imI=/trim/fit-in/800x800/filters:format(webp)/https%3A%2F%2Fstorage.googleapis.com%2Farvutitark-prod%2Fpublic%2Fmedia-hub-olev%2F2022%2F11%2F251940%2Forigina.jpg

Can the source URL be hidden by using the same SECURITY_KEY for encryption? So the URL would be smth like this instead: https://thumbor.arvutitark.ee/xIPGHvXZ8VkGc8JPgCW0SqQ_imI=/trim/fit-in/800x800/filters:format(webp)/xxxxxxxxxxx, where xxxxxxxxxxx is encrypted. Or even the entire path after the hash could be encrypted: https://thumbor.arvutitark.ee/xIPGHvXZ8VkGc8JPgCW0SqQ_imI=/xxxxxxxxxxx.
