That's the fun part...If you don't INCLUDE the patch on Patreon...It's fine. At least it has been for me. I post it on my personal site, and on another forum that has no issues with that content. My patch is never mentioned on Patreon, and people know, or at least SHOULD know they can ask via private message for it, or go to my website.
You can even claim plausible deniability by saying the patch was made by a 3rd party and it is "unofficial" and not supported.
