according to Install /e/OS on a Fairphone The Fairphone (Gen. 6) - “FP6”

If you plan to relock the bootloader after the installlation

this is not mandatoty, and only available with Official version, why relocking ?

Most important thing to take care about is the “android Security Update" aka "Security Patch Level” date (SPL) included in the already installed Operating System on your device at time of the unlock.

It must be OLDER than the “android Security Update" aka "Security Patch Level” date (SPL) included in the /e/OS build you want to install, otherwise you risk to change your device into Brick.

• You will find this information about stock OS on the device :

settings --> about phone --> android version 15 --> android security update

• you will find this information about /e/OS build on the release article about the /e/OS version you want to install :
  the title of the article need to match both “/e/OS version” and “android level”,
  currently "e-3.2-a15"
