Can I cut installed Vinyl Fencing?

there are two panels of my installed vinyl fence that need to be higher due to drainage problems. These panels are facing the driveway while the others are on the sort of an L shape. Anyway, can i cut and what would I need to do and what tools would I need. If I can't cut what other option do I have. I just don't know so please don't criticize me for the questions i ask.
