moderncv modify right margin or length of cvitem

I am trying to edit my resume, and I have trouble managing the spacing on the cvitem. I'd like it to be of a shorter length, more specifically I want the line ending to be less than the other elements.

Here I have an itemize inside the cvitem. Basically I want the entire cvitem to be of shorter length. I tried modifying some of the moderncv classes, but to no avail. Help appreciated. Thanks!

EDIT: The code here

    \documentclass[12pt,a4paper,sans]{moderncv}

\usepackage{verbatim}

% moderncv themes
\moderncvtheme[blue]{banking}                 % optional argument are 'blue' (default), 'orange', 'red', 'green', 'grey' and 'roman' (for roman fonts, instead of sans serif fonts)
%\moderncvtheme[green]{classic}                % idem

% character encoding
\usepackage[utf8]{inputenc}                   % replace by the encoding you are using

\usepackage[scale=0.93]{geometry}
.....
\begin{document}
....

• Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – Herr K.

You can modify \cventry so that its content is inside a minipage. Put these lines in your preamble:

\renewcommand*{\cvitem}[3][.25em]{%
\ifthenelse{\equal{#2}{}}{}{\begin{minipage}[t]{15cm}\hintstyle{#2}: }{#3}\end{minipage}%


and adjust 15cm to your needs.

MWE:

\documentclass[12pt,a4paper,sans]{moderncv}
\usepackage{verbatim}

% moderncv themes
\moderncvtheme[blue]{banking}                 % optional argument are 'blue' (default), 'orange', 'red', 'green', 'grey' and 'roman' (for roman fonts, instead of sans serif fonts)
%\moderncvtheme[green]{classic}                % idem

% character encoding
\usepackage[utf8]{inputenc}                   % replace by the encoding you are using

\usepackage[scale=0.93]{geometry}

\renewcommand*{\cvitem}[3][.25em]{%
