Obama has on multiple occasions tried to dissuade VP Biden from running for president. First, in 2016, Obama pressured Biden to sit out the race because he believed Hillary Clinton was the best shot at continuing his legacy. Even though that didn't pan out for Obama, he still tried to talk Biden out of running in 2020.
From the NYTIMES: "The two men spoke at least a half dozen times before Mr. Biden decided to run, and Mr. Obama took pains to cast his doubts about the campaign in personal terms."You don’t have to do this, Joe, you really don’t," Mr. Obama told Mr. Biden earlier this year, according to a person familiar with the exchange.
Mr. Biden — who thinks he could have defeated Donald Trump four years ago—responded by telling Mr. Obama he could never forgive himself if he turned down a second shot at Mr. Trump."
It's all right here in this CNN Report:
Obama: Joe, don't embarrass yourself buddy.

"Obama actively tried to discourage Biden from running this time and that Obama warned Biden’s aides to make sure Biden didn’t embarrass himself or damage his legacy by running for president." pic.twitter.com/eigdWqnW2Z
