Except if AMD decides to release some kind of update, there is no way.
The CPU is physically (as literally burned into the silicon) locked to Dell. Forever.

I've heard that putting any retail 7742 into a Dell locks it. If that is so then it could be ( I am guessing ) a blown out capacitor on the backplane.
I dont think its on the silicon, that would require substantial additional investment.

AMD processors are shipped unlocked from the factory, and can initially be used with any OEM’s motherboard. But once they are used with a motherboard with PSB enabled, the security fuses will be set, and from that point on, that processor can only be used with motherboards that use the same code signing key.

I am not so sure that this is a physical thing. I had a colleague that was doing some testing for amd and had gotten a few loaner cpus (7763 and 7713). He was also testing on some dell r7525s that were his own. He mentioned that amd was able to "reset" the cpus somehow when he was done testing and shipped them back.
