Is it possible to force a package to be called last in the entirety of the LaTeX, when called in the class...
I have designed a class that needs the xepersian package. This package is unique in the way that it needs to be called last so it doesn't get overwritten. I usually define my packages in the class file using the "RequirePackage".
Is there a way to force a package to be called last where it is called in the .cls file with the possibility of other packages being called using the usepackage in the .tex file?

You can useAtBeginDocument{RequirePackage{xepersian}}.

@campaAfterEndPreambleis too late to load a package. You'll get aLaTeX Error: Can be used only in preamble.. TheAtBeginDocumentis the latest a package can be loaded because right after that the preamble ends (i.e. preamble-only commands become error messages).

@UlrikeFischer Ah, yes, there's that. If I recall correctly, there's an infamous Brazilian class file which does something like that and loadinghyperrefon top of it is a nightmare :-)

You can delay the package loading using AtBeginDocument:
AtBeginDocument{RequirePackage{xepersian}}
this will put the package loading after the .aux file is read but before the “proper end” of the preamble, where all the preamble-only commands are redefined to throw an error; from this point on any usepackage (or RequirePackage) will not work.
If the package, for some reason, needs to be loaded before the begin{document} even starts, then you can load the etoolbox package and use:
BeforeBeginEnvironment{document}{RequirePackage{xepersian}}
this will execute the RequirePackage before executing anything from the begin{document}. The effect is the same as if you had put the RequirePackage line right before begin{document} in your .tex file.

Of course, you can always load xpersian in the preamble (before hyperref). It will not be loaded twice.
