if your package is for 10.0.1 then it should work fine in any 10.X you could just try multi targetting for 11 by doing something like this in your prj file

json
  <PropertyGroup>
    <TargetFrameworks>net7.0;net6.0</TargetFrameworks>
  ......
</PropertyGroup>

  <ItemGroup Condition="$(TargetFramework) == 'net7.0'">
    <PackageReference Include="Umbraco.Cms.Web.BackOffice" Version="11.4.2" />
    <PackageReference Include="Umbraco.Cms.Web.Common" Version="11.4.2" />
    <PackageReference Include="Umbraco.Cms.Web.Website" Version="11.4.2" />
  </ItemGroup>

  <ItemGroup Condition="$(TargetFramework) == 'net6.0'">
    <PackageReference Include="Umbraco.Cms.Web.BackOffice" Version="10.6.1" />
    <PackageReference Include="Umbraco.Cms.Web.Common" Version="10.6.1" />
    <PackageReference Include="Umbraco.Cms.Web.Website" Version="10.6.1" />
