Is it possible to cache node_modules that were installed in Dockerfile?

I need to install sharp inside the Dockerfile to make Next.js image optimization run properly (see docs). sharp is quite large and significantly increases build time. Is it possible to somehow cache this part?

It's natively possible using the official Docker build-push-action via buildx, but not yet possible using this action.
