Splitting BCH/BSV stored on a Ledger Nano device

Hi there,

I had my BCH stored on a Ledger device since before the BCH/BSV fork and I made no BCH transactions since. I've been traveling in the meanwhile and now I regained access to my Ledger Nano S and I'm searching for a way to split the coins. The Ledger support website recommends using the Electron Cash Splitting tool, but this project is now out of date and the developer posted a 'warning' asking people to avoid using it due to phishing vulnerabilities.

I also check this guide on the BitcoinSV website. I understand that in order for this method to work I would need a prior Electron Cash install.

Is there any safe way to make the split on windows?
