NEED TO CHANGE XFX to SAPPHIRE RX570

NEED TO CHANGE XFX to SAPPHIRE RX570

hey so i have an xfx rx570 4gb card and i installed macos catalina on a
i5 3470s
8gb ram
xfx rx570
and the installer didnt show unless i changed to the igpu and i successfully installed the macos catalina but now when i boot to it with the rx570 it doesnt show an output
but when i boot with the igpu it shows only the cursor and black screen im pretty sure because the igpu isnt supported because its an intel hd 2500 and now i need to use the dgpu but first i need to change the bios to sapphire but i get this message so any help?
