Will setting the percent_peers_to_restart = 0 prevent a rolling restart?

No, regardless of that setting, a minimum of 1 peer will be restarted per round:
From server.conf spec:

percent_peers_to_restart = <integer between 0-100> 
* suggested percentage of maximum peers to restart for rolling-restart 
* actual percentage may vary due to lack of granularity for smaller peer sets 
* regardless of setting, a minimum of 1 peer will be restarted per round
