Version upgrade to epoll v4.0.2

is it possible to create a version that works with Node v20 ?. I get the following error when using "onoff": "^6.0.3"

Error: The module '/home/me/temp/pi-io/node_modules/epoll/build/Release/epoll.node'
was compiled against a different Node.js version using
NODE_MODULE_VERSION 115. This version of Node.js requires
NODE_MODULE_VERSION 108. Please try re-compiling or re-installing
the module (for instance, using `npm rebuild` or `npm install`).
