Need EDL files for Surface Duo 2

Stuck in bootloader (fastboot) menu. Initially was able to get to the recovery menu and tried to sideload via adb the image file downloaded from Microsoft. When I rebooted it went into a bootloop and will not go into recovery menu. Since I did not unlock bootloader in Android prior to crash I believe my only option is to try EDL to get the system recovered/restored to working state. Where can I get the necessary EDL files for this effort. Thanks
