SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
Another alternative is to install a third party launcher directly onto the other drive. A bonus to this method is that many of these other launchers will keep your installations separated by default so you don't have to do it manually, and will also make installing mods and modpacks much easier. I can highly recommend MultiMC, which I use myself because it supports Linux and Mac as well as Windows. I have also heard good things about GDLauncher, and there are other decent launchers out there as well.
