No it's not. A Horcrux is so evil that even in that book it's only mentioned without the method. Thats why Riddle had to ask Slughorn how to do it after reading that book.

They only do so with Items that were created by Goblins. Since he created that himself they can't reclaim it.

But Voldemort is a narcissistic psychopath who would never believe that someone would be able to do the things he did.
