Are body scanners mandatory at Charles de Gaulle airport?

Currently considering different options to fly from Spain (Schengen, EU) to Tokyo (non-Schengen, Japan). One of the options is to do a layover in CDG (Charles de Gaulle - Paris). I would like to determine whether body scanners are mandatory in CDG security checks, as this will directly impact my choice of airport for flight connections.

To provide some detail (even when this is not the point of the question): I consider those an unacceptable breach of privacy. Currently some are said to show a layout of the human body and not the whole surface; but still concerned about the initial retrieval and possible leak of raw data, disregarding post-processing techniques. Unfortunately, not flying is barely an option, as this is a work travel.

From the terminal connection page at CDG site, there is the following info:

• From EU to Tokyo: passport check only (possibly using PARAFE).
• From Tokyo to EU: arriving at terminal 2E, need to move to 2F (flight back to another country within EU). Moving from 2E to 2F implies passport+security check. I have read that CDG has implemented body scanners, but not sure if those are in this route.

In the website of Aéroports de Paris it also says that "random inspections can be carried out by the security agents, in accordance with the European regulations"; which seems a lax way to say that "anything can happen".

Question: can anyone confirm from first-hand if it is required to go through body scanners at Charles de Gaulle airport when performing a layover in a route between Schengen and non-Schengen countries (and viceversa); and in that case, if opt out is a possibility and what is the alternate screening method? E.g. pat down or something more intrusive.

According to the contact team at Aéroports de Paris, CDG does not have full body scanners that show the entire body and that they use "traditional" X-ray machines (walk-through metal detector). I am however intrigued about whether X-ray are used in metal detectors or if this refers to X-ray backscatter scanners (as I thought X-ray was prohibited on security checks to humans in EU).
