How to setup a default format in LibreOffice Write

How to setup a custom default for LibreOffice Write

What defaults do you wish to change?

Always use the native ODF file formats for your documents. Export a copy of the document at the end of the editing into foreign file formats - if it necessary anyway. (ODF: Open Document Format - .odt, ott, ods, ots, odg otg, …)

Maybe you mean a default template? See Help, Creating and Changing Default and Custom Templates
