How to build nuget package from nuspec without platform version?

I am trying to build a nuget package only for dependencies consisting of 3rd party packages. If I'd be starting from scratch probably adn empty project with reguired assemblies might be a better idea but I already have nuspec files available so I don't want to create my own projects for future safty. Here is one such nuspec file:

<?xml version="1.0" encoding="utf-8"?><package xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://schemas.microsoft.com/packaging/2013/05/nuspec.xsd"><metadata><id>MyCompany.TestPack</id><tags>Test</tags><version>1.0.0</version><authors>Example Inc.</authors><owners>Example Inc.</owners><description>This package provides data.</description><language>en-US</language><licenseUrl>https://example.com</licenseUrl><requireLicenseAcceptance>true</requireLicenseAcceptance><dependencies><group targetFramework="net6.0-windows"><dependency id="DevExpress.Data" version="[22.2.9]" /></group></dependencies><frameworkReferences /><developmentDependency>false</developmentDependency></metadata></package>

And here is the nuget command to build package:

nuget pack my.package.nuspec

Problem is it fails with error:

NU1012: Some dependency group TFMs are missing a platform version:net6.0-windows

I also tried /p:WindowsTargetPlatformVersion=7 with nuget command without success.
But if I change targetFramework="net6.0-windows" to "net6.0-windows7.0" or 10 etc., it works.
My question is, how can I build package from above nuspec with out providing platform version? or if it is necesssary then how can I set it through nuget command?
