\begin{frame} 
    \frametitle{Some string}

    \begin{itemize}

        \item Knuth

Answer 1

You have (at least) two options:

• Insert the instruction \thispagestyle{empty} immediately after the \titlepage instruction.

• As @Werner has already noted, you could move the instruction \setbeamertemplate{footline}[page number] to after the title frame.
