Unfortunately, if you are talking about the Avast User Interface (?), that isn’t easily done or the point of setting it is reduced.
The only way is to do a clean reinstall of Avast, see below - You also don’t say what Avast Program you are using, if a Paid version, you are going to need your be able to log on to your Avast Account from the new installation.
