Removal of auto date calculation on termination page

Summary: Hi, We are trying to remove the auto date calculation on "termination take effect" field. We just want this date to be blank and should not auto calculate the date based upon the "termination notification date"

Content (required):

Currently if user puts the "termination notification date" as 1 October 2022 then system is auto calculating the date as 1 November on "termination take effect" date field (adding 30 days to it). I have no idea where do we store/setup this information.

Version (include the version you are using, if applicable):
