Disclaimer I've never done it myself but I've looked into it in the past. It doesn't seem like its too overly complicated. Just be sure to check out their features per device when deciding which surface to go with: https://github.com/linux-surface/linux-surface/wiki/Supported-Devices-and-Features#feature-matrix

You could get a surface and install your favorite flavor yourself: https://github.com/linux-surface/linux-surface
