You can use Basic Tools ->Resize Data and select your dataset. Then in the same file selection dialog, you can choose to do a Spatial subset which gives you the option to use an ROI/EVF for the subset. This will only create a rectangular area as small as your vector layer. If you want to mask areas outside the bounds of an irregular vector layer, you can convert the vector to an ROI and use Basic Tools ->Subset data via ROIs and choose to mask the areas outside the bounds of the vector.
