I would also have a look at the XDA forum. A very large percentage of devices that are not officially supported have unofficial ports (Lineage and others) that run 99% as well as the official ones.

e.g. my old Galaxy S8 was not official supported but one of the staff members of XDA made a port that runs like an absolute dream.

Check the unofficial builds on XDA. My bet is that it exists. The unofficial builds are rock solid if you're wondering. I have a 10 year old smartphone that runs Lineage18 flawlessly on an unofficial ROM
