Even if I believe that it’s too early (can’t found anything for this device @ GitHub) I would suggest you to:
- Retrieve device’ specs (done)
- Start from xda and search for LOS-based customs in order to grab sources/device trees (and, why not, try ask there if someone can build \e\ for you): https://forum.xda-developers.com/f/asus-zenfone-9.12653/
- Share infos you’ve collected (don’t forget tags), like this: https://community.e.foundation/t/samsung-galaxy-a10-exynos/43255
If you’ll recieve no responses, consider building \e\ yourself by folloqing this guide:
https://doc.e.foundation/support-topics/build-e
And/or this other (for beginners):
