how to limit the modify the permission of USB files on MacOS?

I have a MicroSD storing some files and I want to limit the permission to "read only" when it is ejected from my Mac. I checked the "Get Info" menu but the "Sharing & Permissions" is unchangeable, as in the fig:

So is there any solution to change this property or should I use some third-party products?

MacBook Pro 13″, macOS 11.2

Not sure what is USB files...


Typically SD cards have a manual "lock" which makes it read only....



SD/SDHC/SDXC memory card is write protected or locked ...





You have some control from >System Preferences>Security & Privacy>Privacy


both Full Disk access / Files & folders access



Change Security & Privacy General preferences on Mac ...
