Run independient replicas into production

GROMACS version: 2020.6
GROMACS modification: Yes


I want to run production, but I want to make several replicas independently, I am using an NPT assembly for production and I am turning off the continuation command, and adding the following code,

; Velocity generation
gen_vel = yes; assign velocities from Maxwell distribution
gen_temp = 300; temperature for Maxwell distribution
gen_seed = -1; generate a random seed

it would be correct?
