Moving core from internal drive to external drive

I am really green to coding. I bought the 1tb umbrel. It’s not enough storage to hold bitcoin core. I need instructions on how to move it to the Sandisk extreme ssd external 2tb drive I have plugged in. When I ask a python gpt, it’s confusing .

I use a 1tb and it hold bitcoin core and a few other apps with room to spare.
