You can have what you call the "explicit mode" if you set the variable
bidi-display-reordering to nil. This only supports the LTR explicit
mode, though. Personally, I don't see when would the RTL explicit
mode be useful: there's no RTL-only text in real life, so some
reordering is always required. But maybe I'm missing something.

Like I said, you are welcome to test the rest of your requirements and
ask questions if you think something is not supported or isn't working
