Stop Big Sur from writing Spotlight and other files to external MSDOS format volumes (SD cards)
I have an M1 MacBook Pro running Big Sur 11.4 and I have occasion to worm with MSDOS formatted external media (typically SD cards). Big Sur keeps writing various Spotlight and other files to my SD card even though I have tried to add my external volume to the "Privacy" table in Sys Prefs even after I use Disk Utility to format the SD card. Is there any way to prevent Big Sur from writing files to the SD card that I don't tell it to write? This causes havoc with some embedded devices that get confused if they see these "foreign" files.
Here is an example of all the junk that Big Sur writes to my MSDOS (FAT16) formatted SD card, none of which are useful to me:
/Volumes/ECOWITT> sudo ls -laR

Note also the ridiculous system protection that prevents me, as root, from even looking at, let alone deleting, these files.
Does Big Sur have an "I am not a noob and need to have my hand held" mode flag that I can set?
Of note is that Windows 10 does not write random files to external media.
Thanks for any help.
