Is there a way to use external font files with unicode-math?

Question

I use fontspec with LuaLaTeX to load fonts from external file even if they are not installed on the system. Such as

\usepackage{fontspec}
\setmainfont[Path=fonts/,
             Extension=.otf,
             UprightFont=*-Regular,
             ItalicFont=*-Italic,
             BoldFont=*-Bold,
             SmallCapsFont=*-AllSC,]{EBGaramond12}

I also use unicode-math, because it's awesome, usually with XITS Maths for the operators and numbers and EB Garamond for the letters.

\usepackage[math-style=TeX]{unicode-math}
    \setmathfont{XITS Math}
    \setmathfont[range=\mathbfsfit/{greek,Greek,latin,Latin}]{EB Garamond}

Is there a way to combine these packages to use the letters from the local EB Garamond instead of the system's one?

Answer 1

Thanks to @Khaled Hosny, I have found out how to do it. It is not exactly true that all fontspec options are available for unicode-math. In this case, unicode-math doesn't seem to support the wildcard expansion feature of fontspec, so instead of

\setmathfont[
    range=\mathbfsfit/{greek,Greek,latin,Latin}
    Path=fonts/,
    Extension=.otf,
    UprightFont=*-Regular,
    ItalicFont=*-Italic,
    BoldFont=*-Bold]{EBGaramond12}

one has to use

 \setmathfont[
    range=\mathbfsfit/{greek,Greek,latin,Latin},
    Path=fonts/,
    Extension=.otf,
    ItalicFont=EBGaramond12-Italic,
    BoldFont=EBGaramond12-Bold]{EBGaramond12-Regular}
