What I’m trying to do

I have managed to get a portable version of Obsidian working on my office laptop. However, due to the locked-down / admin settings, I am unable to install gdrive and thus unable to sync my notes. I have searched for a plugin that can sync my notes to/from Google Drive but have not found any specific to Google Drive. Do you have any suggestions to get around this besides buying a subscription?
Thanks and Best regards.

Things I have tried

I searched the comunity plugings but cannot find a method to directly save and load to good drive.

Can you recommend a a different method to sync with good drive?
