innodb_lock_wait_timeout cant change it
in-order to change innodb_lock_wait_timeout default value you need to edit you my.cnf file and look for innodb_lock_wait_timeout if the parameter exist then you need to edit the current value to 600 and restart the service, otherwise you need to add the parameter innodb_lock_wait_timeout = 600 and restart the service. 
Demo:
my.ini content (I am using windows here, but MySQL) configuration is the same


Re-staring MySQL service and check if the parameter value changed
