Velocity scale at patial dimensions

Dear LAMMPS user:

I intend to use “Fix Langevin” to scale the temperature for the desired atoms. However, I need to only scale the velocity in –Y & -Z direction, & keep vx unaffected. I didn’t find this means in manual. How can I achieve this?

Thanks & Best Regards!

try using a bias via compute temp/partial
