In the manual of arara, there are only two options for latexmk: clean and engine.
However, as similarly done before in this answer and this one, I need to figure out to pass more options of the engine (e.g. lualatex) such as synctex, shell-escape, and interactionmode=nonstop (I am not sure if the last option makes sense with latexmk or not).
Furthermore, is it possible to pass the options of latexmk itself to arara such as -silent?
