There is some training material here: https://github.com/tianocore-training/Tianocore_Training_Contents/wiki.

If you look at BaseTools/Conf/tools_def.template you will see "Supported Tool Chains", which includes VS2019.

When you run edksetup script, it creates Conf/tools_def.txt based on the template. And it makes Conf/target.txt. If you change target.txt TOOL_CHAIN_TAG to VS2019, you should be able to build successfully. I haven't tried it personally, but all the pieces seem to be in place.
