No. The cleartext secret is required as an input for computing OTP codes. The hash does not contain enough information.
You can encrypt the secret before storing it in the database, and decrypt it before using it. However, you'll have to manage your key storage then, so you end up with the same problem of secret storage as before.

There is no solution to the problem. All OTP libraries require the cleartext secret. It is because the OTP protocol works like that.
