Just come across the following thread which discuss about subsetting issues using WKT/Shape format.

How do creat subset image by vector polygon using S1-toolbox?

This would make anything outside your vector no-data-value. If you source product does not have the vector you need, you can use the vector/import-vector operator to add a shape file to the product.
