This presumes that you have ADB working and have already installed an alternate Android launcher on your GL4. If you haven't done any of this, check out this post before proceeding.

Here we go. Note that our Nook can be a bit stubborn about responding to ADB commands, so if it doesn't work the first time, try again and/or ask for help!

1) Download the GL4 firmware to your desktop or laptop from here.

2) Unzip the file.

3) Look for boot.img in the unzipped file and transfer it to your GL4.

4) Download the Magisk app from here and install it on your GL4. (Note: that link is also a very helpful source of info for Magisk.)

5) Run the Magisk app.

6) You'll see two slightly shaded boxes, entitled Magisk and App, respectively. In the Magisk box, directly to the right of the word Magisk, tap Install.

7) Under "Select and patch a file", select the boot.img file you just copied to your GL4. If you don't see this option in the first Magisk window you arrive at after tapping "install", tap "next" and you will.

8) Once Magisk completes its work on your boot.img, it will say so and will tell you where the patched file is located.

9) Copy the patched file back to your desktop/laptop. You can use ADB pull if you wish.

10) Enter the command adb reboot bootloader on your desktop/laptop.

11) Then, this command: fastboot flash boot the name of your magisk-patched boot.img. (I italicized that to indicate that you type the name of your Magisk-patched file instead of what's in italics!!) You can copy and paste the Magisk-patched file instead of typing out its full name. Tap Enter or Return, depending on what laptop/desktop you have.

12) Reboot to system. You can try adb reboot system or simply turn off your GL4 and turn it back on. You should be rooted now. Check by running the Magisk app once you are rebooted. Under the Magisk heading, besides "Installed", you should see a number. If you see "No", it didn't root properly. You can also install a root checker app to check root.

I hope I haven't missed anything!
I was going to give this a try on my Nook GL 4e last night, but I ran into some trouble at step 11. Fastboot didn't seem to be doing anything in the terminal on my Mac. It got stuck on <waiting for devices>. When I ran fast boot devices, nothing happened. I'm thinking this might just be an issue with drivers or something, so I might try it on another machine tonight, but I'm curious if anyone has any ideas as I've seen this same issue mentioned before.

Since I put this on hold for right now, I figured it's probably a good time to make sure that I have the right update file. I downloaded one that I saw linked in another thread, but I'm wondering if anyone could link the current 4e update file here just to be safe.

Thanks!
