Identify when affected Items' server methods are being invoked on Express ECO Release/Revise?

I have some Custom BOM Item Types controlled by the Express ECO.

 

On the custom Items we have the on Before Update and On after Update Server Events responsible for formulating the name(based on some specific field values) of these Items.

Is there a standard way to ensure that the server methods are not called while the Items are promoted to the released state from the Express ECO(Release/Revise)?

P.S. When it is called the On Before Update Method doesn't receive the entire context of the affected Item and sets the name to blank value.

Thanks :)
