The best Android alternative from a privacy standpoint forr the Fairphone 4 is iodéOS, which is a privacy-focused fork of LineageOS that fully supports the device (including re-locking of the bootloader). LineageOS isn’t really a privacy-focused project, but it would also come with some improvements over stock. You can also get a version of LineageOS with microG here.
I’m not sure, but you can always try asking on their forums or in their Matrix chat. It’s a friendly community.
