Running chmod on the link would as you said change the file, but there would still be no effect on the link itself: it would still be 777. The point being that changing the link is a pointless exercise, the actual target should be modified directly if this is required for some reason, but I cannot see a reason for changing any of the ones suggested.

NAME
set link - Changes the value of a modifiable, single-valued attribute of a soft link
SYNOPSIS
cdscp set link link-name attribute-name = attribute-value
ARGUMENTS
The full name of the soft link. The name of the attribute to be modified. Specify only one attribute at a time. See Description for
valid attribute names. The value of a particular attribute.
DESCRIPTION
The set link command changes the value of a modifiable, single-valued attribute of a soft link. The following are valid attributes: Speci-
fies the full name of the directory, object entry, or other soft link to which the soft link points. Specifies a timeout value after which
the soft link is either checked or deleted. The timeout value contains both an expiration time and an extension time. If a soft link
expires and its target entry is deleted, the soft link is deleted. If the soft link still points to an existing entry, its life is extended
by the expiration time. Specify expiration-time in the format yyyy-mm-dd-hh:mm:ss (year-month-day-hour:minute:second). Specify extension-
time in the format ddd-hh:mm:ss (day-hour:minute:second).
Privilege Required
You must have write permission to the soft link.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.
EXAMPLE
The following command redirects a soft link named /.:/admin/work_disk from its current destination name, /.:/admin/work_disk01, to a new
destination name, /.:/admin/work_disk03. cdscp> set link /.:/admin/work_disk CDS_LinkTarget = /.:/admin/work_disk03
