I recently got an i9-14900K and noticed it's running at 1.412V to 1.430V in the BIOS. I'm using a PRIME Z790-V AX motherboard, but I'm not sure how to undervolt it. I thought I found the right setting, but when I set it to offset, I can't change any values. I'm really concerned that my CPU might be failing, and I want to take the right steps to prevent further degradation, especially if I have to replace it in the future.

You might be looking at this the wrong way. Instead of undervolting, consider disabling the power boost feature or capping the maximum CPU frequency. Undervolting can actually risk damaging your CPU, which is the opposite of what you want to do! Also, I'm curious—why do you think the CPU is failing? It's known to run hot, but usually, it's good at protecting itself unless it's been tweaked improperly.
I have to disagree with you here. Undervolting doesn't damage a CPU. In fact, it can help extend its lifespan and improve performance. If your BIOS allows a global offset, try reducing it by about 100mV. You'll want to look into Load Line Calibration (LLC) modes too, as they can help with undervolting without instability. Oh, and syncing your performance cores can also make a difference!
