I think the answer may be it depends. The Foundation for Peripheral Neuropathy has quite a lot of information on the topic - https://www.foundationforpn.org/causes/alcohol/.

It is nerve damage. I know that if the person quits, the damage may stop, but it is my understanding that it is permanent nerve damage, however, I am not a doctor. I am a recovering alcoholic. I was lucky that I did not get neuropathy, however, I have friends who do and they continue to drink. There is a lot of information you can find online.
