Need VS 2017 to build plugins in 4.25?

So I just copied the command from the console, pasted it into the console, fixed the -2017 to -2019 and then it built just fine, leaving me with source files, binaries, ini files, resources etc. Clearly this is not the final step in the process of creating a plugin and yet that is where I come to a halt. Start in UE4, continue on the command line and then never complete the process since I have no idea what UE4 was going to do next. If only I could get UE4 to call the bat file with something other than -2017 then everything should work just fine but where do I tell it what version to use? I see it compiles SOME stuff in 2019 and then at one point it swaps over to 2017 (which I have never had on this brand new machine) and that is where the build dies. Where can I tell UE4 what version of VS to pass to the bat???
