Unfortunately no way to unblock, you may be blocked or locked from all banking services from SBI till now,
Happened with me last week, had to visit home branch to unlock, after that you need to reset your yono , NetBanking credentials with the help of branch,
Then you need to create fresh request for virtual DC , as current one will be removed from your account,
This is my personal experience I'm telling
No I will never use phonePe using sbi dc
