to install just the signingtools from the winsdksetup.exe (available at the same url as the windows sdk iso mentioned above) this is an option to, straight from the Dockerfile i'm working in: RUN powershell Start-Process winsdksetup.exe -ArgumentList '/features OptionId.SigningTools', '/q', '/ceip off', '/norestart', -NoNewWindow -Wait
so if you're in windows then that'd be: winsdksetup.exe /features OptionId.SigningTools
winsdksetup /h gives you the options, so i won't summarise them here. I include the dockerfile snippet, as that is what i started my day looking for the solution for.
