Unable to uninstall out of support Microsoft.AspNetCore.All

I have tried using the .NET Uninstall Tool to remove some items that Windows Endpoint Protection is reporting as out of support. An example is a set of old versions of Microsoft.AspNetCore.All from C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All.

On my system I have these:
2.1.13
2.1.15
2.1.18
2.1.19
2.1.20
2.1.24

EndPoint protection is flagging all except the most recent as having vulnerabilities and being out of support.

I used Add/Remove programs and uninstalled older .NET SDKs. But these were left. I tried the .NET Uninstall Tool but it does not list these.

So... what is the process for clean up? In other folders like C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App I have even more 3.X and 5.X items left... despite only ever using Add/Remove programs (or VS Modify options) to uninstall SDKs/Runtimes etc.

Thanks.
