Why are my add-ons and toolboxes not uninstallable?

I've been following the documentation to uninstall some toolboxes/add-ons from the MATLAB infrastructure I manage.
Initially, I used matlab.addons.installedAddons which returned two values as expected - "MATLAB Coder" and "Signal Processing Toolbox". When I then ran matlab.addons.disableAddon or matlab.addons.uninstall I was presented with the error "not supported for MathWorks products, MathWorks toolboxes, or support packages".
I then tried using matlab.addons.toolbox.installedToolboxes with a view to using matlab.addons.toolbox.uninstallToolbox, however the first command returns empty values so I can't uninstall using that method.
I'm completely limited to the command line (ubuntu 20.04) so I can't open matlab and uninstall from the UI unfortunately. I feel that this may be a bug as I don't see how my products don't fall under either the add-on or toolbox banner, but I'd be grateful for the thoughts and advice of the community. My MATLAB version is r2021a.

Hello,
I understand that you are having trouble uninstalling the add-ons and toolboxes.
Here are the few steps that you can follow for uninstalling MATLAB add-ons and toolboxes:
  • To uninstall a Toolbox: Use this command.
matlab.addons.uninstall(‘Toolbox Name’);
  • To uninstall a Specific version of Toolbox: Use this command.
matlab.addons.uninstall(‘Toolbox Name’, ‘version number’);
  • To uninstall an add-on: Use this command.
matlab.addons.uninstall(name);
Please refer the documentation link below for uninstalling MATLAB addons and toolboxes:
Uninstall add-on - MATLAB matlab.addons.uninstall (mathworks.com)
Thanks

I also could not uninstall Matlab Toolbox (tried twice using GUI and the uninstall finished but as Matlab restarted, the Toolbox was still there).
Your instruction did not work.
>> matlab.addons.uninstall("Deep Learning Toolbox");
Error using matlab.addons.uninstall (line 106)
Using matlab.addons.uninstall to uninstall MathWorks products and support packages is not supported.

I'm facing the same issue. As noted by Trong, when I try to uninstall a given addon, I recieve the error:
>> matlab.addons.enableAddon("DM")
Error using enableAddonWithNameOrIdentifierAndVersion (line 96)
Enable/Disable not supported for MathWorks products, MathWorks toolboxes, or support packages.
Error in
matlab.addons.enableAddon (line 44)
enableAddonWithNameOrIdentifierAndVersion(NameOrIdentifier);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The error is vague and apparently this is the only thread I could find online that even mentions this error... it would be great if a matlab representative gave this issue a closer look...
