有人negotiate过竞争协议的时长吗？

楼主接了个NYC的intern offer，里面有签12个月的竞争协议，要求
Accordingly, and understanding that the Company' s business is potentially global in scope, I further agree that I will not, during the twelve (12) month period following the termination of my employment (the “Post-Employment Period”), directly or indirectly, work for or provide service of any kind, as an employee, consultant, director, owner or in any other capacity, to any person or entity (including any business in planning or formation) that is or intends to be competitive with, or is engaged in the design, development, manufacture, production, marketing, sale or servicing of any product or the provision of any service that relates in any way to the business then being conducted or planned by the Company and any of its subsidiary or affiliated entities.

因为只是实习，很有可能之后楼主会找到和实习公司有竞争关系的全职offer……（其实已经找到了QAQ，而且新公司也在纽约QAQ）

想问一下这种情况下可以和HR negotiate把12个月缩短到3个月吗？给全职的公司已经知道这回事了，而且同意楼主在实习结束3个月后来上班。

确实有点不知道怎么跟intern公司开口，想听听大家的意见。
