Biblatex: Change order of fields (note+pages) for inproceedings/incollection

Question

I'm using the following to change the order of note and pages fields for @article.

\renewbibmacro{note+pages}{%
  \printfield{pages}%
  \setunit*{\space}%
  \printfield{note}%
  \setunit*{\addcomma\space}%
  \newunit
}

I struggle to find something similar for @inproceedings. I guess the note+pages marco is not used there. How can I find out which macro is used instead?

Following moewe's suggestion, I use xpatch's \xpatchbibdriver to remove the \printfield{note} and then to add it before the \usebibmacro{doi+eprint+url}:

\begin{filecontents}{\jobname.bib}

  annotation   = {This is a typical \texttt{inproceedings} entry. Note the

                  \texttt{indextitle}, and \texttt{indexsorttitle} fields. Also
                  note the \texttt{eventdate} field.},
  note = {This is a note},
  url = {https://fake.url}
}

@inproceedings{salam,
