Is CrossFireX supported?

There was a question about the choice of a new graphics card.
Plans to supply two graphics cards that support CrossFireX technology. At the same time, taking into account the performance tests and price range, I give a clear preference to AMD, especially the RX 5700 TX.
But then there was a problem, because the developers decided to abandon this technology for this graphics card, however, many stores note that it supports the technology CrossFireX.

For example, a Citylink store (the filter only noted the price from 30k and crossFireX support)

And what we see as a result of almost all RX 5700 TX graphics cards

Other stores also have the support of this technology in this card
