Excluding a plist file from a folder - necessary? possible?

I am really trying to leverage the use of my markdown files across multiple applications without duplicating them. For that reason, I want to use Blot and the Notebooks app (by Alfons Schmid) on the same folder of markdown files in my iCloud Drive based Obsidian vault. The issue I anticipate is that Notebooks creates a plist file in the folder, and I don't want that file published or uploaded to Blot's servers.

Normally, I can exclude a file with an underscore; I can prevent it from being published by applying "Draft: True" in YAML. But neither of these options are available with the plist file.

In the past, I have used Blot.im's GIT option and I could create an exceptions list to exclude plist files, but I'd like to try using the (relatively) new iCloud Drive option. Can anyone tell me (a) if I can prevent the plist file from being uploaded and (b) if uploaded, would the plist file actually be published?
