How to remove the comma in title bibmacro for ieee style in biblatex?

Question

I have been doing a long google search to a pretty simple question. In my thesis, I am using biblatex with bibtex as a backend and the ieee bibstyle and have loaded the ngerman language in babel. When I print the bibliography, the first thing that is printed is the author followed by the title which is set in quotation marks. However, at the end of the title within the quotation marks it includes a comma (see below).

All I want is to remove this comma. I found some solutions with bst files, however, biblatex does not use bst files (anymore?). Could you please give me some advice what to do?

Thank you in advance!

EDIT: Added MWE example:

Answer 1

Add the following to your preamble

\DeclareDelimFormat[bib]{nametitledelim}{\addcomma\space}
\renewcommand{\intitlepunct}{}

\usepackage{xpatch}

\xpatchbibdriver{article}
{\newunit\usebibmacro{title}}
{\setunit{\printdelim{nametitledelim}}{}\usebibmacro{title}\printunit{\intitlepunct}}
{}
{}

\xpatchbibdriver{incollection}
{\usebibmacro{title}}
{\setunit{\printdelim{nametitledelim}}{}\usebibmacro{title}\printunit{\intitlepunct}}
{}
{}

Edit

To add space after quotation marks, renew \intitlepunct as follows

\renewcommand{\intitlepunct}{\addbthinspace}

You may also try to replace \addbthinspace with \addspace and see which choice fits you best
