Assuming there are no shorted wires from the break, you could also try putting the laptop into Target Disk Mode, but would require a Thunderbolt cable. There is no need for any video to be seen.
The Touchbar 2016 & 2017 models have a LifeBoat connector on the Logic Board. If you can find a tech with one of Apple's proprietary little black boxes used to interface with the LifeBoat connector, then that would be another option. IIRC, this option also requires a Thunderbolt cable. From reading this forum for years now, I have yet to hear of anyone actually finding an AASP who has one of these devices.....and I've never heard of Apple performing this service since Apple places the burden of data recovery on the end user who should be regularly backing up their data. I have seen a couple of posts where a user managed to fine one online, but it is tricky to use even if you can manage to open up the laptop.
With your new Mac you definitely need to start a backup regimen. People should have frequent & regular backups of their computer and all external media (including the cloud) which contains important & unique data. There are a lot more new ways to permanently lose access to the data stored on the internal SSD of the recent Macs dues to all of the hardware, software, and security changes. With the Apple Silicon Macs there is usually no chance of recovering any data.
Apple does provide backup software with macOS in the form of the Time Machine app, but there are also third party options as well. For many people Time Machine is fine.
