Can someon explain how to use target lock with this? Do you have to modify your hit to a crit before you use a target lock to reroll?

For example if you had no hits or crits on the first attack and you use a target lock to reroll all the dice do you still get to modify a hit to a crit?

Or if you modify your hit to a crit can you still use a target lock to reroll the other dice?

I am not that familiar with the rules if you can modify an attack more than once.
