Yes: the "face" part of the specs above are actually arbitrary ELisp
expressions, so you can do things like:

    (defvar terraform-font-lock-keywords
      ;; other code
      (,terraform--block-builtins-with-type-and-name--type-highlight-regexp
       2 (unless (nth 4 (syntax-ppss)) 'terraform--resource-type) t)
      (,terraform--block-builtins-with-type-and-name--name-highlight-regexp
       3 (unless (nth 4 (syntax-ppss)) 'terraform--resource-name) t)))

Another option is to replace the regexps by functions (which internally
can use the same regexps, of course) and have those functions check (nth
4 (syntax-ppss)) to see if the match is inside a comment (and skip to
the next match if so),
