How to transact my bitcoins after hard-fork without losing the forked altcoins (i.e., bitcoin diamond, BCX, Super Bitcoin, etc) which lack of replay attack protection except for export my private key and recovery phrase?

Current status: In order to gain various hard-forked altcoins, I stored my bitcoins into my hardware Ledger Nano S wallet before hard-fork. After hard-fork, I am going to move my bitcoins from my hardware wallet into exchanges for transaction. As some of the hard-forked altcoins have no replay attack protection and no new launched corresponding wallets by the Dev, if I move my bitcoins to exchanges the altcoins will be moved and I will lose the ownership of these altcoins.

Question: I am wondering how I can use my bitcoins without losing my hard-forked altcoins.

I appreciate your help.
