As far as I know, there is no easy facility to alter a registration number to non-transferable state. I managed it with one of my cars, but it was a risky strategy that I would not recommend as a secure way of doing things. What I did was I transferred another number to the car without securing the retention of the original number, then put the new number on retention and asked for the original number to be re-instated. It worked, and the original number was re-issued on a non-transferable basis; but this was some years ago when the local DVLA offices were around and I could talk to an official with some understanding and sympathy for the procedure. I'm not sure I would like to attempt the exercise today.
