This looks pretty reasonable, but is going to require additions
to the security driver code. In the SetAllLabel method of the
security drivers you'll need to iterate over all smartcards.

I guess there is some /dev/smartcard device that needs to
be accessed and thus labelled here ?

Those cert paths will all need labelling with the 'readonly'
disk label.

There's already a helper API for labelling chardev
configs that can be used.
