You can turn off the "fastupdate" index parameter to disable that,
but I think there may be a penalty in index bloat as well as insertion
speed.  It would be better to use a more conservative work_mem
(work_mem, not maintenance_work_mem, is what limits the amount of stuff
accumulated during normal inserts).
