Recently purchased the Fujifilm GFX 50SII, which, like all the GFX medium format Fujifilm cameras, does NOT use their X-Trans sensor which is in the APS-C mirrorless bodies. It uses a standard CMOS with Bayer filter array. DXO support person seems to think the GFX camera will not be supported because they erroneously believe it to have the Fuji-proprietary X-Trans sensor.

The GFX50s2 is scheduled to be supported according to this page, which also features a link to a page for gear proposals.
