ASRock H310CM-HG4 CSM problem

I bought an rx580 but my computer doesn't recognize it... looking it up I found out that it could be incompatibility with the motherboard and they asked me to turn on the CSM, but as shown in the image I don't have the option to launch csm some reason?

ps: secure boot control always disabled

@tobocojhones Have you tried resetting all BIOS settings to default by pressing the F9 key while in the BIOS Utility menu?
