Hi

I' m on Emacs 30.0.90 and using use-package for org (9.7) and other emacs stock packages. 
I add the following in my :custom section

(org-latex-hyperref-template "\\hypersetup{
 colorlinks=true,linkcolor=black,citecolor=black,pagecolor=black,urlcolor=blue,
 pdfborder={0 0 0},
 pdfauthor={%a},
 pdftitle={%t},
 pdfkeywords={%k}, pdfsubject={%d},
 pdfcreator={%c}, pdflang={%L}}
")

instead of touching org-latex-default.packages-alist. Did that before for specific packages and it was a mess... 

Best, /PA
