Is there a posibility to put on ledger the egld that are already staked?

I do not think, I fully understand the question.

Yes. You have to start with an unused Ledger, and restore your seed phrase to it. The downside is that the seed phrase has already been processed in the comparatively less secure environment of your computing devices (cell and/or computer), and also on the Elrond web wallet server (if you used it previously).
