How to _not_ save startup options in postmaster.opts?

[Ron <ronljohnsonjr@xxxxxxxxx>]

    Pg 14, if it matters.
    
    When doing maintenance (including a giant pg_restore), sometime one
    wants to run with different configuration values (like
    archivemode=off, wal_level=minimal, autovacuum=off, etc).
    
    I could edit postgresql.conf -- or have two of them: one normal, and
    one for doing maintenance -- but if I'm going to restart anyway, why
    not just pass those parameters directly to the postmaster?
    
    Alas, those config values are remembered in postmaster.opts.  But I
    don't want that.
    
    Thus: is there a way to tell pg to not put those options in
    postmaster.opts?
    
    Or is this my only option before restarting for production:
    which postgres > $PGDATA/postmaster.opts
