Did you try the official assembler? https://github.com/facebook/hermes/tree/14248a5d75bec91f0053d0bad54b915b49c97342/tools/hermesc

hermesc -emit-binary -out myfile.hbc myfile.js

You can find the right version of the code for your HBC bytecode version in this file, just look back in history:
https://github.com/facebook/hermes/blame/main/include/hermes/BCGen/HBC/BytecodeVersion.h#L23

You can then compile the whole hermes repo for the commit with the correct HBC bytecode version using the instructions from the README.md and use the resulting hermesc tool that is built among the other stuff.

Edit — Or you can use the following tool in order to compile all the possible HBC bytecode CLI versions easily: https://github.com/lucasbaizer2/hasmer/tree/master/autogenerators
