Alternative Ways To Upload To Google Street View (GSV)

I will be trying to use my Pro2 camera to capture Google Street View videos on a scale that is uncommon (I think). My scale would be an entire County, consisting of several hundreds of miles of roads. Does anyone know if there are alternative ways to send large amounts of data to Google, such as mailing them an external hard drive? Uploading via the pipeline I have available, is impossible.

I have a friend that has access to a much bigger Internet pipeline than I do. He's expressed a willingness to try to upload them for me on a trial basis. Besides the "Upload to Google" button in Insta360 stitcher, are there other ways to upload the videos to Google? If so, would someone kindly explain some of the available options?

Thank you!
