To set these setting during runtime I use the

ceph tell osd.* injectargs '--osd-max-backfills 1'

ceph tell osd.* injectargs '--osd-op-queue-cut-off high'
ceph tell 'osd.*' injectargs '--osd_recovery_max_active 1'
^^ That's what I found in our history. Not sure if the single quotes are
needed around osd.*, but this certainly works.
But I'm not sure if the settings can be applied without a restart as far
as osd-op-queue-cut-off high is concerned. IIRC you can't change this
live, and a OSD restart is needed.

P.s. aOn any node that has admin keyring and cluster connectivity you
can run these commands. Admin host seems like a right place to do so.
