Official LineageOS 17.1 for Fairphone 3/Fairphone 3+

How would I do that? I’ve just looked into the archive that can be downloaded for manual FairphoneOS install over here and it does not look like I would be able to do a partial manual flash using these files. At least not for all the partitions you mentioned here

First of all, please note that the recent LineageOS OTA zip files contain all the partition images and install these automatically. You might not need to do anything manual at all.
Second, the FairphoneOS zip files do contain all the partition images as well, but with different file names and a mapping to translate the file names into partition labels. See the file partition.txt included in FP3-REL-Q-3.A.0101-20210420.163631-user-fastbootimag.zip as an example.
