If you wish to try policies.json
Firefox policies https://mozilla.github.io/policy-templates
HardwareAcceleration https://mozilla.github.io/policy-templates/#hardwareacceleration

The Enterprise Policy Generator https://addons.mozilla.org/firefox/addon/enterprise-policy-generator helps to create the configuration file

Disable hardware acceleration

{
  "policies": {
    "HardwareAcceleration": false
  }
}

Copy/paste the above code (example) into Notepad
Save
Type: All files
policies.json

Then
Create the distribution folder
Move policies.json to the distribution folder
Move the distribution folder to the folder where Firefox is installed

To complement

Preferences Affected: layers.acceleration.disabled

Configuration Editor for Firefox https://support.mozilla.org/en-US/kb/about-config-editor-firefox
Enter a search term layers.acceleration.disabled

[ChristosP]

Actually whatever change I make in about:config is reset after restarting FF

Are you using a user.js file?

Note: There's a Refresh Firefox button in the Firefox Troubleshoot Mode window, if you can't start Firefox normally. You can also do a manual refresh by creating a new profile and transferring your important data to the new profile.

Make a test both in action at the same time.

user.js

user_pref("layers.acceleration.disabled", false);

+

policies.json

{
  "policies": {
    "HardwareAcceleration": false
  }
}

What is the result

If you wish to try/test create a new profile (to see if)
about:profiles https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles
Your current profile, this is the profile you're currently using; it can't be deleted (1)
Create a new profil (2) simply enter the name you want and click Next, then restart Firefox

(2) this is your new profile and don't remove your profile (1)

To return to your profile (1), Set as default profile, then restart Firefox
