Can my company request a 30-day extension for my SETV to apply for a Non B visa?

A user on a 60-day SETV (Single Entry Tourist Visa) is seeking advice on whether their employer can negotiate with Immigration to extend their visa for 30 days, allowing for a transition to a Non B visa. There's a note that typically, Indians may receive only a 7-day extension on this type of visa, and looking for clarity on the limits of extensions and necessary considerations before switching visa types.
