Welcome to the Bunnings Workshop community @Jenny2021. It's amazing that you've joined us, and many thanks for your question.
You might like to share an image of the wall in question, which would assist our members in offering some brilliant solutions.
We've got a fantastic array of screening options to choose from which would cover your wall. Many of the natural screenings would easily contour to the curved surface. Depending on how curved the wall was, you might still be able to use the panel options.
