Proofing pizza dough with an electric oven
No, an electric oven is not especially well suited as a device for speeding up dough proofing.
The closest you can get is by turning the oven on at the lowest level, without preheating, and babysitting it. Provided that you have a standard, large oven, it is unlikely that you kill the yeast - but you really have to pay attention to it, so it is labor-intensive, and not actually surefire.
If you insist on a warm proof, you will have to buy or construct a separate proof device.
