How to prevent http-client.env.json copy to publish directory?

[ahdung]

VS 2022 17.11.5
asp.net core webapi .net8.0 project

I make a http-client.env.json file in my project, see docs, then .csproj become this:

...
<ItemGroup>
  <None Include="http-client.env.json" />
</ItemGroup>
...

and after I published project, this file appears in publish directory, I don't want it, I tried change .csproj to:

<ItemGroup>
  <None Include(or Update)="http-client.env.json" CopyToPublishDirectory="Never" />
</ItemGroup>

Not working, please help.

<None Update="http-client.env.json">
  <CopyToPublishDirectory>Never</CopyToPublishDirectory> (or CopyToOutputDirectory)
</None>
