Setting HTML_OPTS in Emacs eintr Makefile.in

Am looking at Makefile.in for "Introduction to Emacs Lisp" called=20
eintr, to see how one would specify options for html output.

One can get the code from https://ftp.gnu.org/gnu/emacs/

The makefile is found /emacs-30.2/doc/lispintro

There is HTML_OPTS, which is set to --no-split --html

What if the user wants to use=20

--split=3Dnode --transliterate-file-names --node-files

How would one call the makefile?
