The question is unclear. Do you mean you want to remove it from the workflow in THAT issue, or remove it from the workflow the first time any issue goes through it?
If you mean an issue can't pass through it again, you need to set a flag when it passes through in a post function and then check the flag every time an issue would encounter the transition and use a condition on the transition to prohibit it from going through. You will need to have an alternate transition for ti issue to go though that allows it only if the flag is set. That way the issue will only have one transition available to it.
