Is it possible to revoke/generate new seal token?

Hello, forgive me for my bad english.

I’m running a test vault container and during init I have chose to generate 3 token and use 1 to unseal.

Is it possible to change this behavior after vault is already running ?
example: generate 10 token, and ask for 3 token to unseal

Is it possible to revoke some token used to unseal vault ?

Thanks in advance for your help

ok found with rekey.
