You really need to be more explicit in your questions.
What we know is that you had some kind of secured loan and that you want to remove it.
I'm going to assume that the reason you want to remove it is because you either had a lot of late payments or defaulted. Is this correct?
If that is the case then there is nothing you can do. It will disappear in time but there is no way to make it disappear faster.
You can only remove errors not blemishes.
