Impro acting, maybe, or have someone point things out like “don’t you see how impatient he looks?”, etc. - the kind of things parents may do with their kids. Or read a book on etiquette, or hire some kind of body language coach, I’m sure it exists. Or of course a pick-up artist book.
By the way, “There’s no rule, you have to learn it case-by-case” is something I often had to say when teaching French to Chinese students; or rather often it was “there may be a rule underneath all those cases, but I have no idea what it is!”. Often finding the rule for your native language requires significant effort; and some rules you come up may not accurately describe the way the language actually works.
Body language coaching doesn’t just exist, it’s an industry. It is typically associated with public speaking, salesmanship, etc, and there are a lot of places (and books, and online resources, etc) to get training. In fact, one of the linked blogs in the OP, “Paging Dr. NerdLove”, is completely dedicated to helping men who are bad at inter-personal communication with women (i.e. socially awkward) get better at it, which includes quite a lot of body language training.
It’s reasonably well known that body language comprises a significant portion of interpersonal communications, so just like you’d expect with other languages there are quite a lot of resources for learning the language, if you take some time to look for them.
And of course, like any language, the resources are of varying quality and usefulness. But the general idea of “you get what you pay for” holds.
