I have a Dell Chromebook 11 that I bought off eBay for $30. It was locked to an enterprise management policy, however I was able to unenroll it (without using Sh1mmer, which wouldn't have worked anyway since there was no leaked RMA shim). Developer mode was disabled by policy. However, to get around this, I downloaded the earliest possible Chrome recovery image for the board (kefka) which dated to 2017, from chrome100.dev. I removed the RW protect screw from the board, and then used the out of date recovery image to recover the laptop, after which I was able to force it into developer mode without the management policy kicking in. I subsequently installed MrChromebox's UEFI firmware, which installed coreboot, and then booted from my Linux USB.
