Write-protection jumper on Acer CB514-3H-R0D5

[MD7070B]

I have an Acer CB514-3H-R0D5 Chromebook, which corresponds to the board name of Markarth. I notice it is listed as supported on this page, however I am running into a few challenges due to the write protection, which I am struggling to disable. The ultimate goal is to replace ChromeOS with Linux.

I have found pictures of other very similar Acer 514's which have a fairly obvious jumper on the motherboard, which I believe disables the WP. However, I have taken the back off of this model, and cannot see any obvious jumpers. Can anyone please provide some guidance on which is the correct jumper to use to disable WP on this model?
