I can't make my Rx 580 work in High Sierra...

Hi! I bought an Rx 580 8gb for my Hackintosh High Sierra (Dell T3500), because I used my old Nvidia GT 1030 and there were no drivers for Mojave, and I read that Rx 580 is natively supported. After I bought it, I saw that I could not install Mojave because my computer does not have UEFI. I decided to stay in High Sierra. But now it detects my Rx as "Rx 580 7mb". Do I need UEFI to make it work? Thank you so much, and I'm sorry for this long text and for my bad english.
