Before attempting any method, you need a DEP-free admin user established!
To do this, wipe and re-install macOS fresh without internet so the DEP profile cannot be established. Instructions to do so are below.

How to reinstall macOS on supported Macs

• Command-R: When you press and hold these two keys at startup, macOS Recovery will offer the current version of the most recently installed macOS.
• Option-Command-R: When you press and hold these three keys at startup, macOS Recovery might offer the latest macOS that is compatible with your Mac.
  • With this method you must unplug your router until the steps below have already been completed.
• Shift-Option-Command-R: When you press and hold these four keys at startup, macOS Recovery might offer the macOS that came with your Mac, or the closest version still available. 

How to install latest macOS on Unsupported Macs

To disable DEP notifications:

Open terminal, type:

sudo nano /etc/hosts

To the end of this section, add

127.0.0.1       iprofiles.apple.com

The result should look like this:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1       localhost
255.255.255.255 broadcasthost
::1             localhost
127.0.0.1       iprofiles.apple.com

Use Control + O to write then the “Return” key so that it writes over that file, then Control + X to exit.

With this one simple line added, there will be no notifications.

Reboot.

sudo profiles show -type enrollment

Now results in the following error:

Error fetching Device Enrollment configuration: (34006) Error Domain=MCCloudConfigurationErrorDomain Code=34006 "The Device Enrollment server is unavailable. Please try again later." UserInfo={USEnglishDescription=CLOUD_CONFIG_MAX_RETRIES_EXCEEDED, NSLocalizedDescription=The Device Enrollment server is unavailable. Please try again later., MCErrorType=MCFatalError}

1. Download UXTU
   
2. Install
   
3. Run
   
4. Choose Balanced Preset
   
5. Navigate to the Clock Control menu (speedometer icon, 5th from the top home button) 
   
6. Under Curve Optimizer Settings, check the box next to CPU, and set a negative offset (good starting point to test stability would be -10)
   
7. Click Apply Settings in the bottom right-hand corner, and test various synthetics or gaming loads. If you are stable at -10 for awhile, move to -15, then from -15, only drop 1 or 2 “points” to fine-tune if you have any BSODs or crashes. Remember each CPU is different.
   
8. Once you’ve established a stable undervolt, navigate to General Settings (gear icon, 7th from the top home button), enable Start on System Boot, Start Minimized, and Auto Reapply, then Save Settings.
