Does anyone know how to downgrade a protected BIOS? B660-A ROG Strix WiFi D4

Hi. I tried at Intel, but they couldn't help me, nor the forums and specially not their tech support. I'm having issues with my i5-13400 with this board. It's reading temps below ambient in Windows (but BIOS shows CPU temp fine). I am suspecting that some setting in the BIOS is doing something weird with my CPU. Only one person in Intel forums told me "that an offset has been written to the Temperature Target MSR" and he was right. My CPU has an offset of 10°C and the TJMax is now 110°C. What can i do? I tried every setting in the BIOS but i cannot downgrade to the first version that supported 13th gen CPUs. Anyone with an idea or the same issue?
Thanks in advance!
P.S.: coolant temp is above ambient as it should be.

It was the CPU. I replaced it for a 13400F and now everything is ok. Thanks for your help!
