how I can do this my wallet is ledger,I use ledger live for transactions. I think is not possible from there.
You're not able to use RBF by using the Ledger Live since it's not implemented (and I honestly don't know if they're planning on implementing it or not). What you can do, however, is using Electrum alongside your hardware wallet (in this case your Ledger device) and then you'll be able to RBF via Electrum.
You can check the the following link in order to connect your Ledger device with Electrum -
https://support.ledger.com/hc/en-us/articles/115005161925-Set-up-and-use-Electrum Assuming you did the right thing I believe your transactions would show up in the wallet including the one that's being processed (I'm still unsure if this will indeed happen, perhaps other members more experienced will know for sure). If the transaction does indeed happen then all you need is to increase it's fee and you can do that by following the same steps that
this tutorial demonstrates.
EDIT: While looking for your problem I've found
this comment from Ledger Co-Funder over at Reddit that said the following (3 years ago):
RBF is not supported by the current Chrome app - it'll be with the next generation of our apps or you can use it right now with Electrum or GreenAddress/GreenBits
Also, albeit the
Coin Control feature supposedly gives you more control over your coins, here's a caveat :
Allow the transaction to be replaced (Replace-By-Fee): By default, this option is enabled. Replacing transactions allows you to increase the network fees to accelerate a transaction that has not been confirmed yet. Transactions cannot be replaced in Ledger Live yet, so please use another wallet if you need to do so.
