Greengrass group deployment

Hi everyone, I am new to aws greengrass and still trying to learn the ropes around how it works.

Is it possible to update a lambda function to a newer version/alias without redeploying the whole Greengrass group? From the documentation it seems as though redeploying the whole group is the only way to do it. If not, can someone explain why? The reason for asking this is because I am curious to see if I can send a small update (Like making a small change in the lambda function) from the IOT core without stopping the Greengrass core.

Also, I would greatly appreciate any resources to understand AWS IOT Greengrass better. I read the documentation and some courses, but if you have any other suggestions I would love the advice?
