Yes, invoices can be created without applying VAT. 

To deactivate VAT in your account, go to 'Settings > Business information > Tax and Registration' and switch off 'Apply VAT to income and expenses.'

You can also remove VAT for each item line, and include it only at the bottom of the invoice by clicking on 'Options' when creating a new invoice and switching the 'Price Format' to 'NET.'
