adb – Start button broke, USB debugging NOT enabled, need to start phone!

Basically I have a Moto X4 without USB debugging enabled and the start button doesn’t work. I can boot up to AP Fastboot (the screen with the little droid in the background), but I don’t have USB enabled, so when I connect the phone via USB cord to my laptop, ADB won’t recognize it (so I can’t reboot using ADB).

Is there anything I can do!? I don’t want to do anything “security sketchy” here: just start it up to get to the point where I can enter my password/use fingerprint ID.

Would an OTG adaptor work!?
