How to edit a RS256 Json Web Token without keys?

I got a RS256 JWT token. I’d like to change the content of the data part and resend it.
I must add I have neither the public key nor the private key.
Is there a trick to do it ? I know for example it is possible to hack the secret of a HS256 JWT so it could be possible to edit the token and then resend it.
Thank you very much for your help.
