How to use the -drive-impersonate flag?

Completely new to rclone. I have to do a transfer for work. For gdrive transfers, I'm trying to manually change to the one other gsuite account my work has to bypass the 750gb limit.
-Do I have to make a new rclone config specifying a different SA file each time? Can each rclone instance running on a command prompt use the same rclone config or would it have to make a new config for each account?
-If I were to go about scripting on windows to have the account in use switch over, would I have to make a new rclone config at the end of the command. Or could I use the same command prompt.

We don't think it's a good practice to bypass the limits from Google and would request you seek help on a different platform. Closing out.
