On these newer phones, no. If the screen doesn't respond the solution today is to replace the screen.
I do not see any guides on the site for this phone, but the screen can be found here: Moto Z4 Screen - Genuine
For disassembly the usual method applies to Moto: Heat up the back (use caution if it's plastic), disconnect the battery and then the screen. Once you disconnect the battery you MAY be able to pry the screen up without further disassembly but use a bit of caution if you do this. I've done it a few times for frame only work but I generally know how much wiggle room I have when I'm inside the phone or if it just can't be done. When in doubt, play it safe and remove the motherboard.
