You can either change these in your user settings, or per-project you can create a .vscode/settings.json file and add them there.
Filtering
If you work with quite a lot of stories in a project, it can be a bit of a chore to scroll through them all, so you can use setting react-native-storybooks.storybookFilterRegex to filter down the shown stories. If you do this on your user settings then only you will see the changes.
