Set biblatex options after loading

Question

I use biblatex with the following call:

\usepackage[style=authoryear,
  mergedate=false,
  maxcitenames=1, 
  mincitenames=1, 
  maxbibnames=999, 
  minbibnames=999, 
  uniquename=false,
  uniquelist=minyear,
  ibidtracker=context,
  labeldate=true,
  hyperref=true,
  isbn=false,
  dashed=false,
  eprint=false,
  doi=false,
  url=true]{biblatex}

However, because of some templating reasons (*) I want to set the package options separately after I load the package. So I wnat to do something like this:

\usepackage{biblatex}

and then later (but still before the \begin{document}):

\setbiblatexoptions[style=authoryear,
  mergedate=false,
  maxcitenames=1, 
  mincitenames=1, 
  maxbibnames=999, 
  minbibnames=999, 
  uniquename=false,
  uniquelist=minyear,
  ibidtracker=context,
  labeldate=true,
  hyperref=true,
  isbn=false,
  dashed=false,
  eprint=false,
  doi=false,
  url=true]

How can I do this?

(*) The tex file is created by pandoc from a markdown document; pandoc uses a template system wheer the main template already contains a plain call to \usepackage{biblatex} while the local customisations are inserted later (just before the \begin{document}). In these customisations I can easily add biblatex options or I could even reload the package with the style=authoryear option if this were possible.

Imho you can set all your options with the exception of style=authoryear with \ExecuteBibliographyOptions. — Ulrike Fischer, Sep 01 '15 at 06:35
All options except those listed in §3.1.1 Load-time Options of the biblatex documentation can be passed to biblatex with \ExecuteBibliographyOptions. The load-time options are (cite/bib)style, backend, natbib, mcite. — moewe, Sep 01 '15 at 06:51
Can you be a bit more precise what exactly you want to be able to do? — moewe, Sep 02 '15 at 13:03
@moewe I have added some details as a footnote to the question. Hope this helps! — halloleo, Sep 02 '15 at 13:56
You will have to set the style when loading biblatex and it cannot be changed afterwards. You will have to change your template appropriately. (Which seems possible here) See also http://tex.stackexchange.com/q/208296/35864 — moewe, Sep 02 '15 at 14:02
@UlrikeFischer I have now written up a short answer. If you want to add an answer yourself I will happily delete mine. — moewe, Sep 13 '15 at 06:36

Of the many options available for biblatex, there are only very few that have to be set at loading time in the square brackets, all others can also be used with \ExecuteBibliographyOptions later in the preamble.

These exceptions are listed in §3.1.1 Load-time Options, p. 44-45 of the biblatex documentation. They are

backend,
style, bibstyle and citestyle,
and the natbib and mcite compatibility options.

The other options listed in §3.1.2 Preamble Options, pp. 45-60, can be used in \ExecuteBibliographyOptions later on.

With the command \PassOptionsToPackage, you can choose options before loading the package for the first time: if necessary even before your \documentclass preamble, in case that is where the package is loaded.

Example:

\PassOptionsToPackage[style=authoryear,
                      mergedate=false,
                      maxcitenames=1, 
                      mincitenames=1, 
                      maxbibnames=999, 
                      minbibnames=999, 
                      uniquename=false,
                      uniquelist=minyear,
                      ibidtracker=context,
                      labeldate=true,
                      hyperref=true,
                      isbn=false,
                      dashed=false,
                      eprint=false,
                      doi=false,
                      url=true]{biblatex}
\documentclass{article}
…
\usepackage{biblatex}

To my understanding, it adds to the option list, it does not override further options.

Isn't the point of the question to set options after the package is loaded? — Johannes_B, Oct 12 '15 at 18:29
