My HP Pro 3520 Needs Modified Bios

Hello guys, i’m bought a intel core i5-2400 for my HP Pro 3520 AIO pc. Prebuilt installed Pentium G2030. New cpu working but bios says “Unsupported CPU detected, system now power off”. I can’t find anything related to this error. So probably i need a modded bios, i can test if anyone can. Please help me.
