The Steam Deck now supports game transfers on your local network, allowing you to copy installed games from your PC to the Steam Deck without having to re-download them over the internet. While Steam sets it to “Only my own devices by default,” which means you can only transfer games from the devices you’re logged into Steam with, you can also set it to “Only my friends” and “Any user” if you want to get games from a friend or family member’s PC. Unfortunately, Steam doesn’t support game transfers originating from the Steam Deck or PCs in Big Picture mode just yet
