Also raised here: Disable wikilink with rules pragma does not work with transclusion widget · Discussion #6712 · Jermolene/TiddlyWiki5 (github.com)
To disable wikilinks locally in a tiddler, one can use \rules except wikilink
for example
\rules except wikilink
This ''is'' [[HelloThere]] and https://tiddlywiki.com
and this is also HelloThere
This is transclusion <$transclude tiddler="HelloThere" field=title/>
But thhe last line produces wikilink! Why $transclude does not respect the rules pragma here? How disable wikilinks generated by $transclude in this tiddler?
