Make SDCard written data unchangable

Is there any possible way to make the written data on a sdcard unchangable and undeletable but still allow to further write on the still free memory?

No, an SD card is as far as I am aware not able to go to read only mode, where it is not possible to reset it back to writable.

If you have a FAT file system, then I suppose one could make specific files READONLY.
