I personally use rollup/babel to build/transpile my code into a "more widely supported" version before using pkg - this could help you.

Personally, I write all my code using the latest supported node at work (Node 12 in my case), but for our target devices, we have to use Node 8 (due to GCC ver on the embedded device.)

Therefore, I use rollup to transpile my development code down to something that runs on Node 8, and then use pkg to target node 8 / armv7 for the final binary.

YMMV, HTH.
