ICloud and Lightroom Classic syncing working and syncing

I use LR Classic in my studio and would like to be able to use it to review and edit photos remotely at home. I have ICloud Storage and have Adobe Storage too. Instructions say to use a folder on my MAC for photo storage and to exclude that folder from my iCloud syncing. Its a warning at the beginning of info. See next paragraph.

"Do you use Lightroom Classic and Lightroom along with syncing services such as Microsoft OneDrive or Apple iCloud Drive on your computer? To avoid unintentionally consuming your syncing client's online storage, make sure that you exclude the Location for Lightroom Ecosystem's Images in your syncing client's settings. Alternatively, in the Lightroom Sync preferences of Lightroom Classic, you can specify another folder location for downloading Lightroom ecosystem's images that is not marked for uploading to your syncing service's online storage. "  

I haven't been able to figure out how to do either of these options. Please help me.
