System not detecting decticate RTX

When I get in the RTX beta I gave the dedicated graphics for Minecraft to run ray tracing

but It detects nothing,

I have AMD RYZEN 7 with Vega 10 graphics and GTX if 1650 with dedicated ray tracing abilitys but Minecraft doesn't detect it because I don't have "RTX' but I gave the componontes of Rtx

And plus  the ryzon 7 is equal to i7 so that a probem,

Also when I load RTX equivalent it faiks to load because it ispf the problem so please fic it
