Biblatex APA-7 Modification

Question

My university has the requirement to not have a final comma before the ampersand of the final author.

Here's the full cite:

Blinowski, G., Anna, O., & Adam, P. (2022). Monolithic vs. Microservice Architecture: A Performance and Scalability Evaluation. IEEE Access, 10, 20357–20374. https://doi.org/10.1109/ACCESS.2022.3152803

The comma in between "Anna, O., (<-- this here)" and "& Adam, P." needs to be removed. How can I adjust this?

I'm using biblatex as follows:

\usepackage[style=apa, backend=biber]{biblatex}

Any help is appreciated.

UPDATE:

I was able to get rid of this comma. But, I've noticed in Overleaf, that this only works with TexLive 2021 or below. If I switch to 2022, biblatex automatically adds a comma there. \renewcommand*{\finalandcomma}{;} don't replace the comma but adds a semicolon after the comma... So this is super strange to me. Is anyone aware of this "bug"?

\documentclass{article}
\usepackage[backend=biber,hyperref,style=apa,citestyle=apa,cites]{biblatex}
\begin{filecontents}{mybib.bib}
@book{ref,
    author = {Michel Goossens and Frank Mittelbach and Alexander Samarin},
    title = {The LaTeX Companion},
    year = {1993},
    publisher = {Addison-Wesley},
    address = {Reading, Massachusetts}
}
\end{filecontents}
\addbibresource{mybib.bib}
\AtBeginDocument{% this is solving it
    \renewcommand*{\finalandcomma}{}
}
\begin{document}
\begin{itemize}
\item[] A cite: \cite{ref}. 
\item[] A parencite: \parencite{ref}.
\item[] A textcite: \textcite{ref}.
\end{itemize}
\printbibliography
\end{document}

Apparently the comma in this position is not logically a \finalandcomma. See the discussions in https://github.com/plk/biblatex-apa/issues/48 and biblatex-apa is missing commas (and the links there). You can find the current implementation of the comma explained in https://github.com/plk/biblatex-apa/pull/144 (see also https://github.com/plk/biblatex-apa/issues/191).

To get rid of the comma we need to redefine \apablx@ifrevnameappcomma. (But then we still need to reset \finalandcomma so it doesn't kick in.)

\documentclass[american]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage{csquotes}
\usepackage[backend=biber, style=apa]{biblatex}
\makeatletter
\renewcommand*{\apablx@ifrevnameappcomma}{@secondoftwo}
\makeatother
\DefineBibliographyExtras{english}{%
  \renewcommand*{\finalandcomma}{}%
}
\addbibresource{biblatex-examples.bib}
\begin{document}
Lorem \autocite{sigfridsson,companion,aksin,geer}
\printbibliography
\end{document}
