What exactly do you mean? How to add custom config options for external cluster
(/etc/pve/priv/ceph/<storeid>.conf) and locally in the /etc/pve/ceph.conf AKA
/etc/ceph/ceph.conf?
Oh. I was thinking, if the /etc/pve/priv/ceph/<storage>.conf is not favored,
then I could document the usage of client settings in the /etc/pve/ceph.conf.
Well, it is there for external clusters, just not really documented atm. For a
hyperconverged cluster (no monhost line in the storage config, line 185 [0]) it
is ignored [0].
If it is configured, it is then added as `-c` to the RBD command, therefore the
default ceph config is ignored IIUC [1].

Sure, AFAICS the custom <storeid>.conf has been added in 2016 [0]. I did a
quick search in the
admin guide and did not find anything about it.

Then I'll prepare some docs patch. :)
Right now, I am only working out the EC pools (data-pool) parameter. Having the
current
possibilities documented is surely a good idea.
Out of curiosity, do you have to use the custom configs often?
So far it might have been a hand full of times. (that I recall)
Currently we have a small how-to on the website with the /etc/ceph.conf.[0] I
want to update this guide as well.
I took a quick look. JFYI the keyring (and cephfs secret) don't need to be
placed manually anymore with recent versions as the pvesm command can take a
path to those files and will place it at the correct location [2]. GUI patches
for that are currently reviewed.
Once this patch is applied, your guide will hopefully become a bit shorter. Or
longer to cover both cases ;)
Have a great weekend!
