No, Evergreen does not support any Z39.50 update functions at this time,
and as far as I know there are no plans to support update via Z39.50.

If you disable the "maintain control numbers" global flag, then this might
be possible; testing required. Note that that would also affect how control
numbers are maintained for bibliographic records.

If you have administrator access, then you should be able to find this
setting in the staff client under Admin -> Server Admin -> Global Flags. If
not, but you have SQL access to the database, it would be "UPDATE
config.global_flag SET enabled = FALSE WHERE name =
'cat.maintain_control_numbers';"

A simplistic approach to preventing control number maintenance for only
authority records would be to modify the public.maintain_control_numbers()
database function to check for an authority-record specific flag (something
like 'cat.maintain_authority_control_numbers') and have that override the
general global flag.
