How to disable Shared Photo Library on a specific device?

Is it possible to turn of Shared Photo Library on only one of my devices? I have a Macbook with a small amount of storage, and I'm trying to limit photos being stored there. Even with Optimize Storage on, it fills up the drive. Turning off the Shared Photo Library would help some.

I couldn't find any options to turn it off, but maybe I'm missing something. Thanks!
