Hopefully someone knows how to stop this happening...

macOS creates files like '._ <filename>' whenever <filename> is accessed or ._DS_Store in folder roots on non-macOS SMB shares or USB drives.

Is there any way to stop this behaviour?

It's really frustrating ending up with loads of duplicate dummy files and I'm not sure if they also potentially cause any configuration issues with some applications that don't ignore the '.' prefix. I also end up with loads of dummy files on the USB sticks and SD cards I use in the car and the car tries to play each one as a media file...
