You can still ‘Bosman rule’ them - the Bosman rule itself is simply pertaining to the ability for a player to leave his club when out of contract without compensation being required from either the player or any prospective club.
There’s a separate FIFA rule about how long in advance of the end of the players contract that they are free to speak to other clubs. It’s 1 month within the same nation, a specific rule that came into force due to the number of Serie A and La Liga players who were lining up against future employers post-January every year.
Edit - didn’t realise that was two pages back. Had an old window still open on my phone. Oops.
