if you mean a generic "custom configuration" option in NM that lets
user pass arbitrary options to wpa_supplicant, that's not doable for
If instead you mean that NM should gain support for some specific
options, that sounds ok, the only problem is finding which ones. But
note that the purpose of NM is to abstract the complexity of
configuration and so it would be better to expose one single option
(for example "channel-width") that then configures wpa_supplicant with
the multiple options needed to achieve that.

I don't think so, for the interfaces controlled via D-Bus the
configuration comes all from D-Bus.
