How to prevent macOS from popping up "disk not readable" for my external drive without making any change to the disk?

Similar question: [How to get rid of "The disk you inserted was not readable" and auto ignore it? (without installing apps)](https://apple.stackexchange.com/questions/332860/how-to-get-rid-of-the-disk-you-inserted-was-not-readable-and-auto-ignore-it) . However, in their case they were able to create an additional readable volume to prevent this from showing up. In my case, I cannot create such a volume since my disk is full, and my volumes are not adjustable. Also, I am open to open-source app solutions if they exist. **Note:** Differently from the other questions asking how to fix the drive, my intention is to silence this notification/warning, and **keep my drive as is** (disk is already full and volumes cannot be adjusted). This is for an old macBook Air running macOS 11.7. However, if you have an answer for macOS 13 please post too. I have an external hard drive that contains partitions/volumes that are **intentionally** not readable by macOS directly. I hope that when I plug in this drive to my macBook, macOS shall not pop up the dialogue saying "The disk you attached was not readable by this computer", so I do not have to click to ignore it every time. I expect fixes done on macOS, not on my drive because my drive does not need a fix.
