What is the opposite of forceUCI=1 and it is not forceUCI=0 ?

This post discusses an issue encountered when accessing an Environmental Variable Definition record in UCI mode. In this instance, the Environmental Variable Value subgrid displayed access errors, despite the user being a System Administrator, making it completely unacceptable. The investigation revealed that the issue was specific to UCI, as accessing the record in classic form was successful. However, forceUCI=1 did not work, and forceUCI=0 was also unsuccessful. The workaround that did the trick was to use forceClassic=1. The post also includes a list of failed and successful attempts when trying to access the record in different modes. The author has created a ticket with Microsoft support to resolve the issue.
