For now, there's no command to do the same. There is an issue open for nerdctl and it seems that some alternative commands are being implemented.

crictl provides a CLI for CRI-compatible container runtimes.

With crictl we have an option to Remove all unused images similarly to how we used to prune the images using docker cli for docker

Command:

crictl rmi --prune

Since July 2022, nerdctl v0.22.1 do includes:

nerdctl system prune:

Add nerdctl system prune command. Needs --all. (PR 1264, thanks to @junnplus)

And nerdctl image prune (PR 1194) or nerdctl container prune (PR 1180) was added in v0.22.0.
