Hello Ashrya,
Several factors need to be considered before approving a resource quota(ex: GPU) for a project. Your long billing history, usage history, business needs, and proper justification are some of them from the lists of factors.These factors not only ensure the felicitous use of the products but also confirms its impending usage more professionally and adequately.
That's being said, if your Google Cloud Platform account is having a TAM(Technical Account Manager) or CE (Customer Engineer), I would strongly recommend you get in touch with them and explain the urgency of using this product. However, before contacting them, kindly ensure that you have the history of contacting sales and its details.
