What am I doing wrong?

Answer 1

We must use \DTMsetup

% Preamble
\documentclass[11pt]{article}

% Packages
\usepackage[showdow,en-GB,en-AU]{datetime2}
\DTMlangsetup{ord=raise,showyear=true,showdow=true}

% Document
\begin{document}
    % Turn off showdow
    \DTMsetup{showdow=false}
    % Format a date
    \DTMdate{2019-01-01}

    % Turn showdow back on
    \DTMsetup{showdow=true}
    % Format the same date
    \DTMdate{2019-01-01}
\end{document}
