[Feature Request]: Switch config enable/disable NVM

[tupywebteam]

Feature Description

After updating herd, I had the inconvenience of having my settings modified in .zshrc

I use asdf and I have no intention of having nvm, so it is interesting that there is the option to enable/disable nvm in the herd

The best case would be to be able to choose between nvm or asdf

Is this feature valuable for other users as well and why?

Customization setup

I use fnm, and while Herd is a good way to install PHP, I really don't appreciate that it also forces nvm into my environment. This should be optional, and if node is already installed somehow, Herd shouldn't touch it or replace it.
