Force enabling TRIM before setup assistant is run

Question

Basically, I'm preparing to give a MacBook Pro, running Mac OS X 10.11.4, to someone, but I need to execute "sudo trimforce enable" beforehand, as it contains an aftermarket SSD (fully compatible with TRIM). I wanted them to be able to use the normal setup assistant, so creating a user to run the command is not ideal.

Is it possible to boot into recovery or single user mode and run the command, without having to create a user account?

Thank you.

You can boot into OS X Recovery mode by pressing CMD+R at startup, after it boots and OS X Utility comes up, go to Application menu and them Terminal. Then you can execute sudo trimforce enable. You can also boot into single user mode and execute the command (If it doesn't work in single user mode them try taking out the sudo).
