How to use OTF files in ConTeXt?

Question

Is there a way For ConTeXt to use uninstalled .otf files in an arbitrary folder?

In my current LaTeX files, for example, I have:

\setmainfont{ProximaNova}[
    UprightFont=*-Regular,
    ItalicFont=*-RegularItalic,
    BoldFont=*-Bold,
    BoldItalicFont=*-BoldItalic,
    Path=../../fonts/ProximaNova/,
    Extension=.otf]

It picks up the font files from a specific folder where I store all of my fonts. The naming is sometimes different between fonts so they are spec'ed in setmainfont.

The best I can tell from this question and documentation is that ConTeXt needs to read the fonts from some OSFONTDIR, which can be more can one folder, but must be specified in this variable. I can't use just any .otf files, specified directly in the .tex file. Or am I misreading? I don't think I saw anything indicating that typescript can take paths to files?

I don't have the Proxima Nova font, but I just downloaded the Cormorant font, so I'll use this one. Then I use \definefontfamily to set up the font.

\definefontfamily [mainface] [serif] [Latin Modern Roman]
                  [tf=file:Cormorant-Regular.ttf,
                   it=file:Cormorant-Italic.ttf,
                   bf=file:Cormorant-Bold.ttf,
                   bi=file:Cormorant-BoldItalic.ttf,
                   sc=file:CormorantSC-Regular.ttf]
\definefontfamily [mainface] [sans] [Latin Modern Sans]
\definefontfamily [mainface] [mono] [Latin Modern Mono] [features=none]
\definefontfamily [mainface] [math] [Latin Modern Math]
\setupbodyfont [mainface]

\starttext

\samplefile{knuth}

\stoptext

I could have hardcoded the complete file path but that is too unflexible in my opinion. Instead I pass an appropriate value of OSFONTDIR to ConTeXt, as such

OSFONTDIR="~/Downloads/Cormorant_Install_v3.601/1. TrueType Font Files" context test.mkvi
