can we restrict users from accessing other segment values than the one used in shorthand aliases

Summary:

Is there a way where we have the segment values populated by choosing the shorthand aliases stay static rather than allowing the user from changing them from the dropdown option manually while creating an account combination for a journal.
Is there a way to personalize this using page composer or any other means than segment value security and cross validation rules

Content (please ensure you mask any confidential information):

the ask is to make sure that the drop down option's available for the prefilled segments after choosing the short hand aliases should be disabled rather than giving an option for the users to change it
