My boyfriend was deported 1 year ago due to a drug possession and he can't come back for 10 years is there a way to reduce/renter the US sooner?

No, it is not possible. Even if you marry him and file an application for a waiver of the bar to entry after deportation, it will be denied because your boyfriend is *permanently* inadmissible to the United States as a result of his drug conviction. It means that he will never be permitted to come back, not even after 10 years. The only way to remove this permanent bar is to find legal defects in his criminal conviction, re-open the case, and get the court to cancel the conviction. It is a very difficult task, and the chances of success are low. But it is the only possible solution.
