How to export pruned full node for my laptop?

Hey, learning Bitcoin with Linux and need some help.

I'm running a full node on my desktop (Win 10).

I have a fresh install of Ubuntu 18.04 running on my laptop. There isn't enough HD space for a full node (256 GB), so I'm wondering if I can spin up a pruned node on laptop. From the stuff I've seen, it seems like I need to download/sync the full blockchain before I can prune.

Is there a guide that teaches me how to export pruned full node data from Win 10 to Ubuntu? Is there an easier way to spin up a pruned node from scratch?

The goal is to use Coldcard with PSBT (Partially Signed Bitcoin Transaction) on a Linux laptop with my own node.

Thanks in advance!
