Assuming that you know how to get luahbtex and luahblatex.exe:

You need a development version of luaotfload for this:

Marcel made yesterday a release that you can use:
https://github.com/latex3/luaotfload/releases.

Alternatively, if you want to keep track of the development you can
install luaotfload so that it is used with latex-dev:

Get the luaotfload git https://github.com/latex3/luaotfload

Checkout the harfnode-dev branch

Run in the folder with the build.lua

   l3build install

This will install luaotfload in the tex/latex-dev folder of your
texmfhome.

You then need also an luahblatex-dev entry in the fmtutil-sys and a
luahblatex-dev.exe  (a copy from luahblatex.exe).

Build the formats and then you can try. The log-file should
mention a 3.006 luaotfload.



To use harf you must declare the mode when loading the font. And as I
saw yesterday it is also necessary to correctly declare the script:

E.g.

\setmainfont{Noto Sans Tibetan}[RawFeature={mode=harf;script=tibt;}]
