Alphabetic citation style and authortitle style combined with Biblatex

Question

I im using Biblatex as my package with biber as the backend and following package declarations:

\usepackage[
backend=biber,
style=trad-abbrv,
citestyle=alphabetic,
minalphanames=3,
maxalphanames=3,
maxbibnames=99
]{biblatex}
\DeclareNameAlias{sortname}{family-given}

I want the keys of the citations to appear in the alphabetic style e.g.

[Azu97], [LB17], ...

but I also want the names of the authors to appear as family1, given1; family2, given2; ... in the literature.

To top it of, I would like all of the letters of the name to be written in capital in the ACM-manner.

How can I achieve this with biblatex?

This is an example of how I want my citations to look like.

My current declarations end up in a weird mix, where the citestyle in the document is as needed, but in the literature the citations keys are numeric.

Minimal example:

document.tex

\documentclass[a4paper, 
twoside, 
12pt]{scrbook}

\usepackage[
backend=biber,
style=trad-abbrv,
%giveninits=true,
citestyle=alphabetic,
%citestyle=trad-abbrv,
minalphanames=3,
maxalphanames=3,
maxbibnames=99
]{biblatex}
\DeclareNameAlias{sortname}{family-given}
\addbibresource{literature.bib}
\begin{document}

    This is the text that cites something \cite{Shamsee.2015}. 
    
    This is also an important source \cite{Park.20190912}.

    \printbibliography[heading=bibintoc]
\end{document}

literature.bib
