How do I dump my eth pow after the merge from a Ledger/Trezor?

That shit is going to zero so I want to get rid of i sooner rather than later. I have a Ledger and a Trezor HW wallet.

• Where can I see if/when the fork happens?
• Where can I sell them?
• Any replay attacks or other risks to be aware of?
• Any other forks or freebies to be aware of?
