Looks like they don’t. So, the fonts have a glyph for the ligature
code point, but it’s opt-in.

I can see how people could want to only use a subset of ligatures
supported by a font. Fira Code has a ton of ligatures for
multi-character operators in various programming languages, but one
might prefer to enable ligatures only for the operators that actually
exist in the language one is working with. Like, in HTML, --> is a
closing comment delimiter, but in C “while (n --> 0)” only works
because it’s interpreted as “decrement n and check if its old value
was greater than zero”.
