R5 240 not working on Dell Inspiron 620/ vostro 260 board

Hi, I’m using the translator for this so maybe it’s not 100% English. I want to make an r5 240 graphics card work on a Dell Inspiron 620, I already modified the BIOS for anhci support but I want to know if unlocking the other secret BIOS menus could boot the r series on these boards
