Probably there :
[LIST] /e/OS Supported Tablets
.
As link is dead in the dedicated topic for this device,
[UNOFFICIAL BUILD] Google Pixel C (dragon)
Source was there
[UNOFFICIAL BUILD] Unofficial /e/ Builds for Lineage Supported Phones
.
Is /e/ Build from (2019) could be older than stock ?
I don’t think so as the device is from (2015)
edit : sadly, yes it is -->post/15
