Block malicious node operators

Hi,

There seem to be malicious node operators that everyone is likely to be connected with: https://twitter.com/lopp/status/1640730194552975365

The full list of malicious nodes seems to be even bigger: https://b10c.me/data/observations/06-linkinglion/linkinglion-ip-addresses.txt

I would like to check if my Umbrel is conntected to it and block it. Since I am running the latest umbrel version, bitcoin-cli does not seem to be available any more.

Is there a way to perform the check and another to block the nodes?

Thanks!
