To disable Secure Boot:

Enter Surface UEFI (To enter, hold Vol. Up & Power while shut down, or enter Windows Recovery menu > Advanced Options > UEFI Firmware Settings.)
Go to the "Security" tab.
Disable Secure Boot
Go to Boot Configuration tab
Make USB first
Save and exit

Now, continue with the generic-x86_64 guide to install. I recommend using OS Installer package instead of the regular generic-x86_64 package
