Prevent my "Work" Safari profile from syncing to my iCloud account

Hey all!

I have a MacBook Pro, which I use primarily for work, but I also have some personal accounts, bookmarks, etc, that are used on my "Personal" Safari profile. This is the only device where I do anything work related, and I keep all of my work browser activity limited to the "Work" Safari profile.

How can I keep this "Work" profile from syncing to my iCloud account and other Apple devices?
