Yes, assuming your keyboard doesn't have the same problem with it.

You have two options here:
1. Remap with SharpKeys. You then can't use that key for anything except
a modifier. Since it's your < key, you might not want that. Besides
that, I tried getting the press key feature to work, and couldn't, and I
don't know where it is in the list.
2. I can just write an addon that will make NVDA think that key is your
modifier; I have most of the code already. To do that, I need the VK
code of that key.

My keyboard doesn't have that key, so you'll have to find this. Here's how:

Go into the NVDA Python console and paste these two lines in. You'll
then have 15 seconds to hit whatever key you want to find the key code
of, so hit that key a few times.
Once you have the code attached to that key, send it here, I'll fix my
addon and send it to you.

import ui;c = lambda vk, scan, extended, injected: (0,
ui.message(str(vk)))[0]
import keyboardHandler, winInputHook;x=wx.CallLater(10000,
winInputHook.setCallbacks,
keyDown=keyboardHandler.internal_keyDownEvent,
keyUp=keyboardHandler.internal_keyUpEvent);winInputHook.setCallbacks(keyDown=c,
keyUp=c)
