Not in the way the current system works because the publishers are doing nothing, they are just taking the papers as reviewed by the committee as-is.

In fact, with this law, we are most likely going to see is that the universities will automatically hook into something like: https://hal.archives-ouvertes.fr/

When you submit a paper to a journal, your university normally request that you submit your paper to the internal university store. This store will then automatically push your paper to this open access library after X months.

If this moves this way, publishers would have to say: French researchers cannot publish with us any more....
