This is all in user space so no kernel changes are needed.

I was only going to change the '-D' option (delete all). Assuming this was 
typed:

auditctl -D -k shared-key

You have no rules left which is the same as if you did not have the -k added. 
If however, you have this loaded:

-a exit,always -w /tmp/file1 -k file1 -k my-file-key -k ids-file-high
-a exit,always -w /tmp/file2 -k file2 -k another-key -k ids-file-high

auditctl -D -k another-key

will just delete the second rule.

auditctl -D -k ids-file-high

will delete them all.
