how to do a vacuum minimization without electrostatics and periodic boundary conditions?

Dear NAMD users,

I have a long linear chain. I want to remove steric clashes and simulate
for a while in order for the chain to shrink in length. For this purpose, I
can do away without electrostatics and periodic boundary conditions. This
should speed up the initial relaxation.
Could anyone please help me with the input configuration file settings to
accomplish this?

Best regards,
Jose Borreguero
