Change location of blockchain bitcoin download

Hi, I’m very new at bitcoin nodes, I’ve installed umbrel in Ubuntu 22.04.

The question is that I don’t have enough space in the HHD of my computer (256 GB), but I have an external usb HDD (1TB). I didn’t install umbrel at the external USB, so I am wondering if I have to, to avoid to collapse the HDD of my computer because the space is not enough, I didn’t create or order a patch to the external HDD for the bitcoin blockchain.

Thanks in advance and excuse if any imprecision because I’m not very tekkie compared to most BTC users.
