There are a few loan programs that grant exceptions to bankruptcy requirements in the event of extenuating circumstances that can be proven to be outside of your control (i.e. massive medical bills that you used bankruptcy to settle, etc.) however, in order to make the case for this exemption, you would need to make a strong case for your solvency, shown the ability to re-establish your credit reputation since the discharge of your bankruptcy, and would almost certainly have to go through a bank that offers manual underwriting.
Additionally, if you are Native American, the HUD-184 program is a great option for your situation as it allows for a wide latitude in terms of underwriter discretion and is always manually underwritten as there is no automated underwriting system developed for the loan program. There are several great lenders that offer nationwide financing (as long as you're in a HUD-184 eligible area) and would be a great potential solution if you meet the qualifying parameter of being Native American.
